and I see that the LVM resource would fail.
This to me seems to happen randomly, or I fail to spot a pattern.
Shared storage is a sas3 enclosure.
I believe I follow docs on LVM to the letter. I don't know what could be
the problem.
would you suggest ways to troubleshoot it? Is it faulty/failing hardware?
many thanks,

LVM or clustered LVM?
no clvmd
And inasmuch as the resource would start, fs would mount, if I start
using it more intensely I'd get more of block/unblock and after a while
mountpoint resource failes and then LVM resource too.
It gets only worse after, even after I deleted resourced, I begin to
see, eg.:
[ 6242.606870] sd 7:0:32:0: device_unblock and setting to running,
handle(0x002c)
[ 6334.248617] sd 7:0:18:0: [sdy] tag#0 FAILED Result: hostbyte=DID_OK
driverbyte=DRIVER_SENSE
[ 6334.248633] sd 7:0:18:0: [sdy] tag#0 Sense Key : Not Ready [current]
[ 6334.248640] sd 7:0:18:0: [sdy] tag#0 Add. Sense: Logical unit is in
process of becoming ready
This feels like a hardware issue to me. Have you checked the SMART data
on the drives?
I did think that, there is something unsettling about that
hardware I use, specifically the enclosure.
But today I gotten rid of the cluster and enclosure is
currently linked to only one box, single link, and it is
quiet so far... gee..
