so I recently added a 2TB physical volume (PV) to an LVM volume group (VG) with the sole purpose of removing another 2TB PV from the VG. Everything is carried out from webmin.
So once the extra PV was appended to the LVM , remove the excess PV by pressing “remove from VG”. Then webmin asked
Are you sure you want to remove physical volume device /dev/sdc from its volume group? This will result in any data being shifted to other physical volumes within the group.
Once I accepted the website didn’t change (but the loading animation is …loading all the time) . Now, I am stuck in this webmin page which has no progress bar and I don’t know if I should navigate away or leave it as is.
ps shows that
root@samothraki:~# ps aux | grep -i pv root 3436 0.0 0.3 79608 30524 ? S 02:38 0:00 /usr/libexec/webmin-1.660/lvm/save_pv.cgi root 3446 0.0 0.0 17748 1292 ? S 02:38 0:00 sh -c yes | pvmove \/dev\/sdc 2>&1 root 3448 0.0 0.6 68012 52412 ? S 02:38 0:08 pvmove /dev/sdc
something is going on but the command arguments do not make be feel at ease. According to
pvmove documentation, I should be see a source and destination drive as arguments… no?
The big question is how can I verify that the operation is indeed progressing?
vgdisplay don’t seem to notify accordingly….
If you ran
pvmove yourself with the
-v (verbose) flag then you would be able to see progress. But since you ran it in the background through a web app, you are stuck. You will just have to wait it out.
In the meantime, you might want to spend some time learning how the system really works, rather than relying on the crutch of webmin.
