[Lustre-discuss] Lustre quotas using a journaled quota
Howdy! How can I tell if an existing Lustre file system (either 1.6.7.2 or 1.8.3) is using a journaled quota system? I have been reading that if a Lustre file system is set-up using journaled quotas then the command "lfs quotacheck -ug /mnt/lustre" could be avoided following an unclean (crash) unmount of Lustre. Is this true for 1.8.x? Is journaling the quota information analogous to providing an external journal for a file system in that I need only to specify the flag and point to which the quota journal should be written? What are the downsides to an external journal for quota information in Lustre? Note: My questions stem from reading the Lustre 1.8 Operations Manual section 9.1.1 TIA! megan SGI Federal
