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
