Hi all, The server in which i have mounted file system using mount -t ceph is showing below errors in dmesg. libceph: tid 79987 timed out on osd2, will reset osd libceph: tid 81516 timed out on osd0, will reset osd libceph: tid 81133 timed out on osd1, will reset osd libceph: skipping osd1 10.25.12.127:6800 seq 1 expected 2 libceph: tid 80108 timed out on osd2, will reset osd libceph: tid 81134 timed out on osd1, will reset osd libceph: tid 81641 timed out on osd1, will reset osd Is is because of this, write/copy operation in my cluster is slow ? is this a error which needs attention or can be safely ignored ?
These are usually harmless, and could just mean the osds can't keep up with the requests you're giving them. Given your other issues, it might be a symptom of a problem with your osds.
What filesystem are the osds using? Are there any warnings from these filesystems in dmesg?
Thanks Madhusudhan
