Subject: [linux-lvm] Question (and feature suggestions) regarding lvmcache and lvmthin

Message-ID: <54F9D5F9.1030609@gmail.com> (raw)
I've got a couple of cached LV's on my system where the origin is a
RAID{1,10,5} LV, and have noticed that there doesn't appear to be any
way (at least that I can find) of resyncing/scrubbing the origin LV
without detaching it from the cache pool, which is significantly
inconvenient as I scrub the origin LV's weekly. I was wondering if
there was any advice on how to do this without needing to detach it from
the pool
On a somewhat related note, It would be a nice feature for both cached
LV's and thinpool LV's to be able to just run 'lvchange --syncaction
check' on the pool/cached LV and have it scrub each of the constituent
LV's if applicable (ie, if you have a thinpool LV where the data and
metadata LV's are RAID{1,10,5,6}, then running 'lvchange --syncaction
check' on the thinpool would trigger a read-only resync for the data and
metadata LV's).
Please cc me on replies, as I'm not subscribed to the list.
