* libglusterfs: Don't allow '-0' as input value for numbersPranith Kumar K2014-06-221-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: io-stats tries to init log-buf-size as uint32. All gf_string2u*** functions which get the unsigned values from string don't want the string to contain '-'. So the GF_OPTION_INIT with '-0' as value fails init in io-stats, but by that time 'ret' is already reset to 0. Io-stats ends up returning 0 even when init failed. Because of this caller of init thinks initialization is successful when it is not. iostat_xlator->private is still NULL. Because of this when a fop tries to access members of io-stat-private structure, it crashes. Fix: I initially thought may be we should fix all gf_string2u*** functions to accept '-0'. But all these functions are used only for setting volume options. If we accept '-0', gluster volume info shows output as follows: diagnostics.brick-log-buf-size: -0 This seemed ugly, so I felt it is better to disallow '-0' as valid input for numbers. Also fixed return value in cases of failures in io-stats.

* cluster/dht: Do layout self healing of directory for nameless lookupVenkatesh Somyajulu2014-06-171-0/+161
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Currently in the nameless lookup code path, if at the end of the lookup, even if it detects that layout anamolies are there, layout healing will not be done as there is no code to heal it. So there can be race between mkdir and lookup. Assume mkdir is going on from some other mount point, Say, M1. Directories are created on some nodes but layout is not set yet. Now from M2, nameless lookup goes, lookup will be success full as the directory is present on some of the nodes, but it won't heal layout. Now if create goes after lookup fop, because layout is absent, file creation will fail. Fix: Included the code of layout self-heal in the nameless lookup path. At the end of lookup, layout will be computed as it would have been in the named lookup, but it will be set to those node only, where directory is present. So after that if create fop goes, the probabiliy to get the subvolume with proper hash-range is high now, so reduces the race window. Other: Whenever a directory is created, we have to choose a brick from which we start allocating layout in a circular fashion. To calculate this starting brick, I have changed the candidate from name of the directory to gfid of the directory But to compute where a given file belongs, we will still use the name of the file. Hash computed from the name of the file should belong to any one of the directory-hash-range Calculation of hash for a file is acting as a consumer and the setting of directory layout based on gfid is acting as a producer, which are independent from each other.

* glusterd/snapshot : Provide enable/disable option for snapshot auto-delete ↵Sachin Pandit2014-06-131-22/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | feature. This patch provides an interface to enable or disable the auto-delete feature. Syntax : gluster snapshot config auto-delete <enable/disable> DETAILS : 1) When auto-delete feature is disabled, If the the soft-limit is reached then user is given a warning about exceeding soft-limit along with successful snapshot creation message (oldest snapshot is not deleted). And upon reaching hard-limit further snapshot creation is not allowed. Example : ------------------------------------------------------------------ |Case - 1: Upon reaching soft-limit | |Snapshot create : snap successfully created. |Warning : soft-limit of volume (vol) is reached. Snapshot creation |is not possible once hard-limit is reached. | |----------------------------------------------------- |Case - 2: Upon reaching hard-limit | |Snapshot create : snap creation failed. |Error : hard-limit of volume (vol) is reached, Hence it is not |possible to take further snapshots. Please delete few snapshots |of the volume (vol) before taking another snapshot. ------------------------------------------------------------------ 2) When auto-delete feature is enabled, then as soon as the soft-limit is reached the oldest snapshot is deleted for every successful snapshot creation (same as existing method), With this it is made sure that number of snapshot created is not more than snap-max-hard-limit.

* storage/posix: Janitor should guard against dir renames.Pranith Kumar K2014-06-121-0/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Directory rename while a brick is down can cause gfid handle of that directory to be deleted until next lookup happens on that directory. *) Self-heal does not have intelligence to detect renames at the moment. So it has to delete the directory 'd' using special flags, because it has to perform 'rm -rf' of that directory as it is not empty. Posix xlator implements this by renaming the directory deleted to 'landfill' directory in '.glusterfs' where janitor thread will perform actual rm -rf by traversing the directory. Janitor thread wakes up every 10 minutes to check if there are any directories to be deleted and deletes them. As part of deleting it also deletes the gfid-handles. Steps to hit the problem: 1) On a replicate volume create a directory 'd', file in 'd' called 'f' so the directory 'd' is not empty. 2) bring one of the bricks down (lets call it brick-a, the other one is brick-b 3) Rename d to d1 4) When brick-a comes online again, self-heal deletes directory 'd' and creates directory 'd1' on brick-a for performing self-heal. So on brick-a, gfid-handle of 'd' pointing to 'da is deleted and recreated to point to 'd1'. 5) This directory 'b' with all its directory hierarchy (for now just the file 'f') will be under 'landfill' directory. 6) When janitor thread wakes up and deletes directory 'd' and gfid-handle of 'd' without realizing that it is now pointing to 'd1'. Thus 'd1' loses its gfid-handle Fix: Delete gfid-handle for a directory only when the gfid-handle is stale.

* cluster/dht: Fix min-free-disk calculations when quota-deem-statfs is onKrutika Dhananjay2014-06-021-0/+120
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: As part of file creation, DHT sends a statfs call to all of its sub-volumes and expects in return the local space consumption and availability on each one of them. This information is used by DHT to ensure that atleast min-free-disk amount of space is left on each sub-volume in the event that there ARE other sub-volumes with more space available. But when quota-deem-statfs is enabled, quota xlator on every brick unwinds the statfs call with volume-wide consumption of disk space. This leads to miscalculation in min-free-disk algo, thereby misleading DHT at some point, into thinking all sub-volumes have equal available space, in which case DHT keeps sending new file creates to subvol-0, causing it to become 100% full at some point although there ARE other subvols with ample space available. FIX: The fix is to make quota_statfs() behave as if quota xlator weren't enabled, thereby making every brick return only its local consumption and disk space availability.

* glusterd : Volname, brickpath & volfpath length validationAtin Mukherjee2014-05-031-0/+80
| | | | | | | | | | | | | | | | | | | | | | | | While creating a volume and adding a brick validation for _POSIX_PATH_MAX is done on absolute pathname instead of relative pathname due to which a brickpath having less than _POSIX_PATH_MAX may also fail the validation if the directory length is greater than (_POSIX_PATH_MAX -strlen(brickpath/volume name). Also this fix addresses one cli response message correction which says the volume file is too long instead of brick path is too long (when brickpath length validation doesn't fail and vol file length validation fails.) It is also important to note that with the current design of volfile naming, it can not be guranteed that volname and brickpath can have max of _POSIX_PATH_MAX characters.

* storage/posix: do not dereference gfid symlinks before ↵Xavier Hernandez2014-05-021-0/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | posix_handle_mkdir_hashes() Whenever a new directory is created, its corresponding gfid file must also be created. This was done first calling MAKE_HANDLE_PATH() to get the path of the gfid file, then calling posix_handle_mkdir_hashes() to create the parent directories of the gfid, and finally creating the soft-link. In normal circumstances, the gfid we want to create won't exist and MAKE_HANDLE_PATH() will return a simple path to the new gfid. However if the volume is damaged and a self-heal is running, it is possible that we try to create an already existing gfid. In this case, MAKE_HANDLE_PATH() will return a path to the directory instead of the path to the gfid. To solve this problem, every time a path to a gfid is needed, a call to MAKE_HANDLE_ABSPATH() is made instead of the call to MAKE_HANDLE_PATH().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GlusterFS protocol currently uses AUTH_GLUSTERFS_V2 in the RPC/AUTH header. This header contains the uid, gid and auxiliary groups of the user/process that accesses the Gluster Volume. The AUTH_GLUSTERFS_V2 structure allows up to 65535 auxiliary groups to be passed on. Unfortunately, the RPC/AUTH header is limited to 400 bytes by the RPC specification: http://tools.ietf.org/html/rfc5531#section-8.2 In order to not cause complete failures on the client-side when trying to encode a AUTH_GLUSTERFS_V2 that would result in more than 400 bytes, we can calculate the expected size of the other elements: 1 | pid 1 | uid 1 | gid 1 | groups_len XX | groups_val (GF_MAX_AUX_GROUPS=65535) 1 | lk_owner_len YY | lk_owner_val (GF_MAX_LOCK_OWNER_LEN=1024) ----+------------------------------------------- 5 | total xdr-units one XDR-unit is defined as BYTES_PER_XDR_UNIT = 4 bytes MAX_AUTH_BYTES = 400 is the maximum, this is 100 xdr-units. XX + YY can be 95 to fill the 100 xdr-units. Note that the on-wire protocol has tighter requirements than the internal structures. It is possible for xlators to use more groups and a bigger lk_owner than that can be sent by a GlusterFS-client. This change prevents overflows when allocating the RPC/AUTH header. Two new macros are introduced to calculate the number of groups that fit in the RPC/AUTH header, when taking the size of the lk_owner in account. In case the list of groups exceeds the maximum possible, only the first groups are passed over the RPC/GlusterFS protocol to the bricks. A warning is added to the logs, so that most system administrators will get informed. The reducing of the number of groups is not a new inventions. The RPC/AUTH header (AUTH_SYS or AUTH_UNIX) that NFS uses has a limit of 16 groups. Most, if not all, NFS-clients will reduce any bigger number of groups to 16. (nfs.server-aux-gids can be used to workaround the limit of 16 groups, but the Gluster NFS-server will be limited to a maximum of 93 groups, or fewer in case the lk_owner structure contains more items.)
