Hello there,
We have a disk usage update problem. 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.
