Do you do things like[1] with the vm's?
[1] echo 120 > /sys/block/sda/device/timeout -----Original Message----- From: Francois Legrand [mailto:f...@lpnhe.in2p3.fr] Sent: donderdag 25 juni 2020 19:25 To: ceph-users@ceph.io Subject: [ceph-users] Re: Removing pool in nautilus is incredibly slow I also had this kind of symptoms with nautilus. Replacing a failed disk (from cluster ok) generates degraded objects. Also, we have a proxmox cluster accessing vm images stored in our ceph storage with rbd. Each time I had some operation on the ceph cluster like adding or removing a pool, most of our proxmox vms lost contact with their system disk in ceph and crashed (or remount system storage in read-only mode). At first I thought it was a network problem, but now I am sure that it's related to ceph becoming unresponsive during background operations. For now, proxmox cannot even access ceph storage using rbd (it fails with timeout). _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
