* storage/posix: do not dereference gfid symlinks before ↵Xavier Hernandez2014-05-222-8/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | 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().

| | | | | | | | | | | | | | | | | | | Bug 990887: During a blocking NLM call NFS server is crashing. Cause: When nlm4_establish_callback function is called from nlm4svc_send_granted the cs->req->trans pointer is NULL. Thus using this pointer will result in a crash. Whereas cs->trans points to a valid transport object. NLM should use cs->trans instead of cs->req->trans. Fix: Replaced cs->req->trans with cs->trans.

* dht: dht_lookup_dir_cbk should set op_errno as local->op_errnov3.4.3beta1shishir gowda2014-03-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Two glusterfs clients return inconsistent errnos when the bricks of the volume were down. Consider two gluster mounts. Mount 1 was done when the bricks were online. Mount 2 was done after the bricks were killed, (using the 'glusterfs' command instead of the mount script). For any request, mount 1 will return ENOTCONN, where as mount 2 will return ENOENT. This happens because for the 2nd mount, a fuse would send a lookup on '/' for any request, as it hadn't been done yet. The client xlator returns ENOTCONN, but the dht_lookup_dir_cbk changed this to ENOENT unconditionally when aggregating. So, fuse returned ENOENT, even though the errno should have been ENOTCONN. backporting http://review.gluster.org/6072 BUG: 1019095 Change-Id: Iaa40dffefddfcaf1ab7736f5423d7f9d2ece1363 Original-author: Kaushal M <kaushal@redhat.com> Signed-off-by: shishir gowda <gowda.shishir@gmail.com> Reviewed-on: http://review.gluster.org/6471 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Harshavardhana <harsha@harshavardhana.net> Reviewed-by: Anand Avati <avati@redhat.com>

* protocol: pass the size of the data in the WRITE on-wire FOPNiels de Vos2014-02-102-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | Capturing GlusterFS traffic with tcpdump and displaying it in Wireshark shows that the size of all WRITEs are 0 bytes. It seems that the attribute is not used, and the size is calculated an other way. Even if the size attribute is not used (yet), it should be set correctly to prevent confusing while debugging network traffic with Wireshark or other tools. Note that the on-wire format is not being changed with this patch. The size is already part of the structure that is exchanged between the client and server.

A valid check is necessary here to avoid errorneous move to destination where the space could be scantily available.

* core: fix errno for non-existent GFIDAnand Avati2013-11-269-12/+23
| | | | | | | | | | | | | | | | When clients refer to a GFID which does not exist, the errno to be returned in ESTALE (and not ENOENT). Even though ENOENT might look "proper" most of the time, as the application eventually expects ENOENT even if a parent directory does not exist, not returning ESTALE results in resolvers (FUSE and GFAPI) to not retry resolution in uncached mode. This can result in spurious ENOENTs during concurrent path modification operations.

| | | | | | | | | | | | | | | | | | | | | | | | | This is (arguably) a hack to work around a bug in libvirt which is not well behaved wrt to using TCP ports in the unreserved space between 49152-65535. (See RFC 6335) Normally glusterd starts and binds to the first available port in range, usually 49152. libvirt's live migration also tries to use ports in this range, but has no fallback to use (an)other port(s) when the one it wants is already in use. libvirt cannot fix this in time for their impending release. This is submitted to gerrit to provide some minimal visibility upstream to justify hacking this change (as a temporary patch) into the glusterfs-3.4.1 RPMs for Fedora 18-21 until libvirt can fix their implementation.

This also affected the showing of asynchronus task status in 'volume status' command. By not resetting the status prevent the above issues from happening. Since we use the running/not-running of the rebalance process as the check when performing other operations we can safely leave the rebalance stats collected on an add-brick.

* glusterd: Calculate volume op-versions only on set/resetv3.4.1qa2Kaushal M2013-09-133-6/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/5568 The volume op-versions are calculated during a volume set/reset, reading a volume from disk and importing a volume during probe or volume sync. The calculation of the volume op-version depends on the clusters op-version as some features are enabled automatically depending on the clusters op-version. We also don't store the volume op-versions persistently and don't export the volume op-versions during sync. Due to this, there can occur cases which will lead to inconsistencies in volumes in different peers. One such case is below, Consider, a cluster made up 3 peers P1, P2 and P3, operating at op-version N. The cluster has two volumes V1 and V2, which have volume op-versions N (since volume op-version cannot be greater than cluster op-version). We have, Cluster-op-version = N V1 op-version = N V2 op-version = N A set operation on V1 causes the clusters op-version to be bumped up to N+1. Assume that there exist some features that are automatically enabled on op-version N+1. The op-version of V2 remains at N as no operation has been performed on it. So, Cluster op-version = N+1 V1 op-version = N+1 V2 op-version = N Now, we probe a new peer P4. On the new peer we will have the following op-versions, Cluster op-version = N+1 V1 op-version = N+1 V2 op-version = N+1 This happens because we don't send volume op-versions during the sync after probe. P4 will freshly calculate the op-version of V2 (assuming features have been auto enabled due to the cluster op-version being N+1) as N+1. Another case is when glusterd on a peer restarts. Assume P3 was restarted, glusterd will recalculate the volume op-versions during the restore state. Again, op-version of V2 will be calculated as N+1 assuming auto enabled features. This will lead to inconsistency in the volume representation in memory and on disk, as glusterd will assume the volume contains auto enabled features, but the volfiles don't contain them as they were not regenrated. These kind of issues can be solved by calculating the volume op-version only when features are enabled and disabled (ie. during volume set/reset), persisting the volume-op-versions and exporting/importing them.
