Hello again, The problem has gone after I run the "lfs quotacheck -ug /RS" command. This is interesting though... Seems like the file usage statistics are not updated automatically. But it's my solution for this problem: turning of quota and then running quotacheck... Does anybody have an idea about this.

You can find our software related info below. Here is my problem description: We enabled disk qoutas on our lustre file system. But not using quota, just for checking users' lustre disk usage. It's a quicker way to getting disk usage than using traditional du command. But we have a problem now: Users's disk usage not decrease when they deleted files. Here are the command outputs of du and lfs quota commands for one of our users: [r...@d001 ~]# lfs quota -u guryel /RS Disk quotas for user guryel (uid xxx): Filesystem kbytes quota limit grace files quota limit grace /RS 1564665872 0 0 183 0 0 [1564665872 kbytes ~ 1.47 Tbytes] [r...@d001 ~]# du -smh /RS/users/guryel/ 22M /RS/users/guryel/ Here are our lustre, os and interconnect info: Lustre Version: 1.6.5.1 OS: RHEL 5.1 Clients are connected to servers via infiniband network. I saw some bug tickets on bugzilla. But bugs are related to older version of lustre (1.6.3). So are there anyway to recover that usable space without any upgrade or filesystem down time? What kind of additional info is needed to solve this problem? Thanks in advance. Ender GULER System Administrator HPC Center Istanbul Technical University Turkey
