Hi,
yesterday we had had the problem that one of our cluster clients
remounted a rbd device in read-only mode. We found this[1] stack trace
in the logs. We investigated further and found similar traces on all
other machines that are using the rbd kernel module. It seems to me that
whenever there is a swapping situation on a client those I/O errors occur.
Is there anything we can do or is this something that needs to be fixed
in the code?
client setup:
# uname -v
#1 SMP Debian 3.16.7-ckt2-1~bpo70+1 (2014-12-08)
# rbd -v
ceph version 0.87 (c51c8f9d80fa4e0168aa52685b8de40e42758578)
# lsb_release -r
Release: 6.0.10
Cheers,
Sebastian
