Greetings all, I have a small ceph cluster (4 nodes, 2 osds per node) which recently started showing:
root@ocd45:~# ceph health HEALTH_WARN 1 near full osd(s) admin@node4:~$ for i in 2 3 4 5; do sudo ssh osd4$i df -h |egrep 'Filesystem|osd/ceph'; done Filesystem Size Used Avail Use% Mounted on /dev/sdc1 442G 249G 194G 57% /var/lib/ceph/osd/ceph-5 /dev/sdb1 442G 287G 156G 65% /var/lib/ceph/osd/ceph-1 Filesystem Size Used Avail Use% Mounted on /dev/sdc1 442G 396G 47G 90% /var/lib/ceph/osd/ceph-7 /dev/sdb1 442G 316G 127G 72% /var/lib/ceph/osd/ceph-3 Filesystem Size Used Avail Use% Mounted on /dev/sdb1 442G 229G 214G 52% /var/lib/ceph/osd/ceph-2 /dev/sdc1 442G 229G 214G 52% /var/lib/ceph/osd/ceph-6 Filesystem Size Used Avail Use% Mounted on /dev/sdc1 442G 238G 205G 54% /var/lib/ceph/osd/ceph-4 /dev/sdb1 442G 278G 165G 63% /var/lib/ceph/osd/ceph-0 This cluster has been running for weeks, under significant load, and has been 100% stable. Unfortunately we have to ship it out of the building to another part of our business (where we will have little access to it). Based on what I've read about 'ceph osd reweight' I'm a bit hesitant to just run it (I don't want to do anything that impacts this cluster's stability). Is there another, better way to equalize the distribution the data on the osd partitions? I'm running dumpling. Thanks much, JR -- Your electronic communications are being monitored; strong encryption is an answer.
