* Fix some trivial typos.Erick Tryzelaar2009-06-292-4/+4
| | | | | | | I noticed that there were some minor spelling mistakes/typos in some of the source files. This patch fixes the ones I've found. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>

* version check between client/server made more specific to protocol only.Amar Tumballi2009-06-293-9/+14
| | | | | | | | | This patch is a step towards giving compatibility between the versions of GlusterFS. Now onwards, the protocol-version won't depend on release versions. In general, multiple glusterfs versions can have common protocol-version. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>

| | | | | | | | | | | | | | | | | Ref: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=37 earlier instead of path, it used to take port number, which is an option (-o server-port=<port>), now. new syntax is bash# mount -t glusterfs <hostname>:<path/key> [mountpoint] [This patch is backward compatible with earlier syntax] bash# mount -t glusterfs <hostname>:<port> [mountpoint] Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
* server-protocol: interpret the 'op' value properly when a packet is received.Amar Tumballi2009-06-231-4/+3
| | | | | | | | | Ref: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=35 The check done earlier was not handling the case when a 'op' is == MAX_VALUE (which is not defined), and used to skip to the next array (like gf_mops[MAX] == gf_cbks[0]) Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
* check if the 'key' is the volume file name itself.Amar Tumballi2009-06-231-14/+34
| | | | | | | | With this patch, one can fetch any volumefile which is not pre-defined in volume file with 'option' in server protocol volume, instead clients can fetch the volume files based on the key name itself [From the confdir only] Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
* mount.glusterfs.in correctness in case of duplicate mountAmar Tumballi2009-06-231-2/+2
| | | | | | | | mount.<fstype> script/program should return success in case when it finds duplicate mounts. It was returning failure earlier. Someversions of automount programs had issues with this behavior. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>

* glusterfsd - build proper mount/fuse structure.Basavanagowda Kanur2009-06-221-2/+17
| | | | | | | | | | while appending mount/fuse to a translator tree, make sure that <xlator_t-of-fuse>->next points to the first xlator in the list of xlators and not the subvolume of mount/fuse. NOTE: tree traversal should always happen through <xlator_t>->children Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
* fuse: instead of having a fixed option list, assemble it using ↵Csaba Henk2009-06-221-56/+40
| | | | | | | | "fuse_opt_add_arg" This makes it easier to adjust the option list, and also reduces redundancy. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>

* local->loc should be filled in dht-mknod()Amar Tumballi2009-06-181-0/+9
| | | | | | | local->loc should be properly filled while creating a linkfile. otherwise this causes the segfault in underlying volume layer (mostly client-protocol). Signed-off-by: Anand V. Avati <avati@dev.gluster.com>

* making dht and nufa's 'min-free-disk' option to take both percent and disk-sizeAmar Tumballi2009-06-184-38/+90
| | | | | | | | | | | Originally from Paul Rawson <plrca2@gmail.com> http://patches.gluster.com/patch/391/ : patch re-submitted with patching guidelines. cluster/distribute, and cluster/nufa uses new option PERCENT_OR_SIZET for its option 'min-free-disk'.

| | | | | | | | | | | Originally from Paul Rawson <plrca2@gmail.com> http://patches.gluster.com/patch/391/ : patch re-submitted with patching guidelines. with this patch, the xlator volume options get another type which can take arguments either in 'percent' or in 'bytes', which is useful in many cases.

| | | | | | | | the current msg is getting printed in warning level. Instead changed it to debug, as the msg specific each node being full is already getting printed in higher priority, hence this msg looks excessive. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>

* change ha-statfs() to handle the case of loc->inode being NULLAmar Tumballi2009-06-172-27/+44
| | | | | | | | | | This fix is needed in ha_statfs(), as the current code doesn't handle the case of loc->inode being NULL, which is a valid case in statfs() [Remember its stateless call]. This was causing 100% disk full logs in distribute or nufa as the logic of checking whether the subvolumes have enough disk space on them used to fail. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
* client: Replace saved_fds dict with listShehjar Tikoo2009-06-152-158/+177

* libglusterfsclient: Call inode_lookup to prevent pruningShehjar Tikoo2009-06-121-5/+7
| | | | | | | | | | | | | This bug shows up while using unfs3 with replicate. The absence of an inode_lookup on a looked-up/created inode results in it getting pruned from the inode table. Consequently, a subsequent lookup for the inode results in a different inode number being returned by replicate. This breaks unfs3 because it tries to remember the inode numbers returned by two different stat-family calls.

* strict check of extended attribute flags while opening a striped fileAmar Tumballi2009-06-112-68/+223
| | | | | | | | | | Added a fd_ctx structure for stripe, which takes care of understanding the extended attribute flags, and opening the right blocks in order (to make sure the read/write operations happen in order). Helps to handle situations like accidentally adding subvolumes to stripe, etc Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
