[Lustre-discuss] Incorrect user's Quota

[Lu Wang]

Dear list,
		We are running a small Lustre with 2 OSS( 1 OSS shares server with MDS ) for usrs' home directory. We have experienced incorrect user's quota for several times. Certain users got "Quota exceed" errors when their usage of the disk 
space is only half of quotas. 
		We have this kind of errors on MDS for some times:
Aug 24 12:25:20 beshome01 kernel: Lustre: Skipped 3 previous similar messages
Aug 24 12:51:29 beshome01 kernel: LustreError: 28467:0:(quota_master.c:507:mds_quota_adjust()) mds adjust qunit failed! (opc:4 rc:-122)
Aug 24 12:52:06 beshome01 kernel: LustreError: 26005:0:(quota_master.c:507:mds_quota_adjust()) mds adjust qunit failed! (opc:4 rc:-122)
	
	Dose this error have relationship with the quota incorrect problem? How can we avoid this situtaion?  

Best Regards
Lu Wang
