Hi,
I have a cluster of 2 servers running 3.7.3 with replication, and standard NFS (no ganesha). This in on CentOS 6.
I use CTDB with 2 virtual IPs (one for each server in a normal situation) to share the volume over NFS and CIFS (samba).
fnctl() file locking doesn't seem to work when the volume is mounted over NFS.
This is apparent with a 'svn info' (svn 1.8 if it made any difference) in a local working copy:
$ svn info
svn: E200033: Another process is blocking the working copy database, or the underlying filesystem does not support file locking; if the working copy is on a network filesystem, make sure file locking has been enabled on the file server
svn: E200033: sqlite[S5]: database is locked, executing statement 'PRAGMA synchronous=OFF;PRAGMA recursive_triggers=ON;PRAGMA foreign_keys=OFF;PRAGMA locking_mode = NORMAL;'
a strace shows:
$ svn info
svn: E200033: Another process is blocking the working copy database, or the underlying filesystem does not support file locking; if the working copy is on a network filesystem, make sure file locking has been enabled on the file server
svn: E200033: sqlite[S5]: database is locked, executing statement 'PRAGMA synchronous=OFF;PRAGMA recursive_triggers=ON;PRAGMA foreign_keys=OFF;PRAGMA locking_mode = NORMAL;'
Everything seems to work fine on native Gluster (FUSE) mounts: the same 'svn info' works nicely.
I can't really use native mounts due to the performance hit (many small files) and the fact I would need to install the gluster client software on every server.
Is fnctl() file locking supported in Gluster NFS mounts? If so, any idea why it doesn't work for me?
Thanks,
Thibault.
