<p>I was hoping I could just remove the storage pool from castle
(since it doesn't seem to be working properly), and then destroy
it, re-create it, and then re-add it and see if that solves the
problem. However, while it seems to exist, it also doesn't (can't
delete it).</p>
<p>Possibly part of the cause of my original problem is that I have
a script that automatically creates a snapshot for each LV, and
this created a snapshot of testvm1_00000 named
backup_testvm1_00000_blahblah.... I've now manually deleted that,
and fixed my script to avoid messing with the VG allocated to
linstor, but so far, there is no change in the current status (as
per below).</p>
<p>Would appreciate any suggestions on what might be going wrong,
and/or how to fix it?</p>
<p>Regards,<br>
Adam</p>

<p>Thank you!<br>

<p>linstor err list showed a list of errors, but the contents
didn't make a lot of sense to me. Let me know if you are
interested in them, and I can send them.<br>

<p>I did a systemctl restart linstor-controller.service on san6,

<p>From this, it looks like san6 (the controller) thinks it has
the up to date data, probably based on the fact it was created
there first or something. The data is syncing to san5 (in
progress, and progressing steadily), so that is good also.
However, castle doesn't seem to be syncing/connecting. <br>

<p>On castle, I see this:</p>
