Hi,
one thing coming to mind is maybe the device names have changed from
/dev/sdX to /dev/sdY? Something like that has been reported a couple
of times in the last months.
Zitat von Alison Peisker <apeisker@xxxxxxxx>:
Hi all,
We rebooted all the nodes in our 17.2.5 cluster after performing
kernel updates, but 2 of the OSDs on different nodes are not coming
back up. This is a production cluster using cephadm.
The error message from the OSD log is ceph-osd[87340]: ** ERROR:
unable to open OSD superblock on /var/lib/ceph/osd/ceph-665: (2) No
such file or directory
The error message from ceph-volume is 2023-08-23T16:12:43.452-0500
7f0cad968600 2
bluestore(/dev/mapper/ceph--febad5a5--ba44--41aa--a39e--b9897f757752-osd--block--87e548f4--b9b5--4ed8--aca8--de703a341a50) _read_bdev_label unable to decode label at offset 102: void bluestore_bdev_label_t::decode(ceph::buffer::v15_2_0::list::const_iterator&) decode past end of struct encoding: Malformed
input
We tried restarting the daemons and rebooting the node again, but
still see the same error.
Has anyone experienced this issue before? How do we fix this?
Thanks,
Alison
