In Nov 2014 we got this CMSTier3Log67 case

   * If =t3fs06= will fail then the =t3ui1*= and the =t3wn*= servers that mount =t3fs06:/shome= will be immediately affected ; if you can't quickly recover =t3fs06:/shome= ( e.g. due to a failed motherboard ) you'll have to umount =/shome= from those servers and mount =t3fs05:/shome2= that is suppose to be an identical copy of =t3fs06:/shome= ; probably you'll need to make symbolic links
   * On =t3fs05= obviously stop the cron sending by rsync =/swshare= to =t3fs06=.
   * Tweak =t3nagios= to forget about =t3fs06=

---+++ User quotas

After upgrading the ZFS version, it was necessary to initialise the accounting information. This can take quite some time...
<pre>
zfs userspace shome
</pre>

User quotas can be set and viewed in the following way (can use name or id for users) 
<pre>
zfs set userquota@3896=500G  shome

zfs get userquota@3896  shome
</pre>

The current usage of all users can be seen with
<pre>
zfs userspace shome
zfs userspace -p -s used shome  # exact value and sorted
</pre>
---++ zfs list -t snapshot   
<pre>

---++ daily snapshots and backup

A script =/root/psit3-tools/regular-snapshot= is called by root's crontab to make a daily incremental snapshot of the =shome= ZFS file system to t3fs05. Users can retrieve files from these snapshots by themselves, as documented in HowToRetrieveBackupFiles. The script also deletes the older snapshots. The script is run by cron.
Look also at the tests for doing incremental snapshot transfers in CMSTier3Log12. 

---+++ ZFS Backup server on t3fs05 - OLD

   * %GREEN% *shome2* %ENDCOLOR%: Backup of shome area
   * %BLUE% *vmshare* %ENDCOLOR%: Backup of virtual machine area (for the older vmware-server based machines)
   * %RED% *swshare* %ENDCOLOR%: cluster's shared software space (e.g. experiment SW)
   * %BLACK% *spare disks* %ENDCOLOR%
