Description
Hello!
We have a problem:
three rbd images are formated and mounted in the system
linux kernel 3.18.35-35
Steps:
1.When we writing/reading data to mounted rbd, all operations looks good.
2.we stopped some osds -> write/read operations are performed normally.
3.But when we start back previously stopped osds, rbd images are stuck:
no read requests are proceed, and DirtyCache pages flush stale.
ceph -s don't show any io request after that. All PG's are ok, health OK.
I'am attach sysrq -t file from node, where rbd's mount.
Please help.
P.S. kernel lib using:
