Hi Brian,
I think I have seen the persistent "UP", too. But I managed to deactivate my
OST nevertheless, by
> root@MDS:~# lctl set_param osc.WORK-OST008-osc*.active=0
And this has to be done on the MDS - to take effect everywhere.
Cheers,
Thomas

My guess is that the trouble is caused by the Bytes added or moved while the quotacheck-scan is running. That gives you an estimate of the size of the
inaccuracy.
We gave the users/groups quota in the order of 100 - 1000 Terabytes. During quotacheck, people would not write more than a few Teraby
had
the same kbytes used...)

Thomas

Hi all,
I have done some "fio" benchmarking, amongst other things to test the proposition that to get more iops, the number of disks per raidz should be less.
I was happy I could reproduce that: one server with 30 disks in one raidz2 (=one zpool = one OST) is indeed slower than one with 30 disks
the clients. I don’t have a good sense
of how serious this is in practice, but I know some larger sites worry about it.

your error messages are all well known - the one on the OSS will show up as
soon as the Lustre modules
