[Samba] Where are People Storing CTDB's Accounting Files?

[Howard, Stewart Jameson]

Hi All,


We're using CTDB to cluster protocols over a large SAN and have had some pain related to a bit of a design flaw:  we store CTDB and protocol-specific accounting files (recovery locks, state files, etc) on the same filesystem that we're offering through CTDB itself.  This makes our front-end services pretty intolerant of flapping in the back-end filesystem, which is obviously not desirable.


We're planning a redesign for this and were wondering what other people in similar environments are doing with the their CTDB shared files.  Specifically, I'm referring to the locations supplied for <shared_dir> in these variables:


/etc/sysconfig/ctdb: CTDB_RECOVERY_LOCK=<shared_dir>


/etc/sysconfig/nfs: STATD_HOSTNAME=$NFS_HOSTNAME -P <shared_dir> -H /etc/ctdb/statd-callout


/etc/sysconfig/nfs: NFS_TICKLE_SHARED_DIRECTORY=<shared_dir>


/etc/sysconfig/nfs: STATD_SHARED_DIRECTORY=<shared_dir>


Thanks!


Stewart
