Subject: bcache hangs with continuous write I/O to SSD device, bcache device stops working
Date: Fri, 22 Mar 2013 13:34:09 +0100 [thread overview]
Message-ID: <514C4FC1.6090804@modelnine.org> (raw)
Hey!
I've checked out multiple trunks over the last two weeks of the current
bcache repository (all 3.8.0+), and they all exhibit the same kind of
broken behaviour: after some time (generally around 6 hours), I/O to the
bcache device stops working (I have layered LVM on top of it, and those
devices also stop working, naturally), and the SSD that's part of the
cache set spins continuously at around 50MB/s I/O on write. It is
irrelevant whether I enable discard or not. I've only tested this with
writeback mode.
Is this a known problem?
