Hi,
I am having a quota issue with Lustre. Here are the default limits
set for an account -
/home 0 400000 450000 189 100000 100000
This sets a quota of about 300 MB or so. After reading the
documenatation, i throught this would have set ~4 G or so, but it is one
zero less. The quota limit is working though.
But today i found the following issue with two accounts. The
account goes over quota showing higher block utilization, while the real
space occupied by the account is only a few megabytes on the filesystem.
Here is an example -
Filesystem blocks quota limit grace files quota limit
grace
/home 307796 600000 650000 221 100000 100000
home-MDT0000_UUID
316 0 102400 221 0 5000
home-OST0000_UUID
307480 0 409600
> du -sh ../username/
3.8M ../username/
In the Lustre server, there are quite a few of the following error
messages -
Jul 24 01:31:09 lustre-3ware kernel: LustreError:
