/usr/sbin/lctl set_param osc.lustre-OST0001-*.active=0

as workarownd on client host, with proper names for filesystem and ost names for all retired OSTs.

We had 'df' hanging on client after we retired some OSTs on 1.8.9 system and now keep this mantra in rc.local .

What client version do you have,  2.5.3  or 1.8.x?

I recently got some help regarding removing an OSS/OST from the file system. Last thing I did was to permanently remove it with (on the MDS):

lctl conf_param ost_name.osc.active=0

This all seems to be working, and on the clients, the command

lctl dl

indicates the OSS/OST is inactive. However, after a reboot of the clients the same command no longer indicates the removed OSS/OST to be inactive. Besides, the command


Takes almost 2 minutes to complete.

Running 2.5.3.
