How to remove OST permanently?
All,

Adding an OST is easy, but how do I REMOVE the small OSTs that I no
longer want to be part of my cluster? Is there a command to tell luster
to move all the file stripes off one of the nodes?

lfs quotacheck gave me an "Input/Output error", while in
/var/log/kern.log I found a Lustre error
LustreError: 20807:0:(quota_check.c:227:lov_quota_check()) lov idx 32
inactive
Indeed, in /proc/fs/lustre/lov/.../target_obd all 34 OSTs were listed
and numbered, but number 32 was missing, instead I had a number 34.
Now, in this test cluster each OSS serves two OSTs. I remember I had
made a mistake with the RAID configuration of about half of the OSTs.
Therefore I had mounted one OST from each OSS, while the others w...
