How to Resync Ibrix Quotas when DU and Ibrix_Edquota Do Not Match

Title: How to resync Ibrix quotas when du and ibrix_edquota does not match

Note: All steps for quota check are performed from the Fusion Manager. (Run parallelly or

serially)

==== Sample scripted steps to do a recommended parallel quota check

1. Stop nfs or samba on the servers [if necessary], then Unmount the file system from the FM:

#/usr/local/ibrix/bin/ibrix_umount -f ifs1

note: ssh to each server make sure a "mount" and/or a "df" does not return ifs1 as mounted and

any server!

2. Before executing the quotachecks we recommend restarting the Fusion Manager and then

quotamonitor to ensure clean process slate for quotachecks.

#/etc/init.d/ibrix_fusionmanager restart

when Fusion manger restarts, then restart quota monitor

#/usr/local/ibrix/init/ibrix_qm restart

3. Spawn the programs on the server[s] owning segments in a shell script executed from the FM,

using the following lines:

note: from your ibrix_fs -i output it appears that only ibrixss1 owns the ibfs1 segments so this is

even easier as we are only running this on one server.

ssh ibrixss1 "/usr/local/ibrix/bin/ibrix_quotacheck -u -g -v -D -Z /dev/ivg1/ilv1 >/tmp/qc_lv1 2>&1

ssh ibrixss1 "/usr/local/ibrix/bin/ibrix_quotacheck -u -g -v -D -Z /dev/ivg2/ilv2 >/tmp/qc_lv2 2>&1

4. You can monitor completion of the above ibrix_quotacheck programs:

for ssh -z -s "ps -elf | grep quotacheck | grep -v grep"

5. From the Fusion Manager Mount the ifs1 file system and synchronize quotas with the following

command sequence:

#/usr/local/ibrix/bin/ibrix_mount -f ifs1 -m /ifs1 <---------- insert FS mount point if different

note: go to the servers make sure the FS is mounted and accessible!

Once FS is mounted run the following sequence of commands from your Fusion Manager:

#/usr/local/ibrix/bin/ibrix_quotamonitor sethostflags -K -k

#/usr/local/ibrix/bin/ibrix_quotamonitor syncnow

#/usr/local/ibrix/init/ibrix_qm status <-----just make sure quota monitor is running! if not run

/usr/local/ibrix/init/ibrix_qm start

6. To ensure quotas stay consistant we have found the following "insurance policy" to be helpful

at other sites.

A. On the FM touch a file named = "ibrix_qmrestart.sh"

B. edit the file and add the following line to it

/usr/local/ibrix/init/ibrix_qm restart

C. copy this new "ibrix_qmrestart.sh" file to the Fusion Manager's /etc/cron.daily/ directory this will ensure the quota monitor will restart daily at 4AM.
