Hello all, Please can someone offer some advice. In ceph.conf, I use: osd_mkfs_type = btrfs osd_mount_options_btrfs = noatime,nodiratime,compress-force=lzo filestore btrfs snap = false However, some of my OSDs are becoming much more full than others, as not all are being mounted with the compress-force option. Is this a CEPH issue or a BTRFS issue? Or other? Take one host. Note that sdc1 is mounted twice, neither of which have the compress-force option. /dev/sdc1 on /var/lib/ceph/tmp/mnt.AywYKY type btrfs (rw,noatime,space_cache,user_subvol_rm_allowed,subvolid=5,subvol=/) /dev/sdd1 on /var/lib/ceph/osd/ceph-16 type btrfs (rw,noatime,nodiratime,compress-force=lzo,space_cache,subvolid=5,subvol=/) /dev/sdc1 on /var/lib/ceph/osd/ceph-15 type btrfs (rw,noatime,nodiratime,space_cache,user_subvol_rm_allowed,subvolid=5,subvol=/) /dev/sdb1 on /var/lib/ceph/osd/ceph-20 type btrfs (rw,noatime,nodiratime,compress-force=lzo,space_cache,subvolid=5,subvol=/) After a reboot, it’s a sdd1 this time. /dev/sdd1 on /var/lib/ceph/tmp/mnt.kWh2NA type btrfs (rw,noatime,space_cache,user_subvol_rm_allowed,subvolid=5,subvol=/) /dev/sdd1 on /var/lib/ceph/osd/ceph-16 type btrfs (rw,noatime,nodiratime,space_cache,user_subvol_rm_allowed,subvolid=5,subvol=/) /dev/sdc1 on /var/lib/ceph/osd/ceph-15 type btrfs (rw,noatime,nodiratime,compress-force=lzo,space_cache,subvolid=5,subvol=/) /dev/sdb1 on /var/lib/ceph/osd/ceph-20 type btrfs (rw,noatime,nodiratime,compress-force=lzo,space_cache,subvolid=5,subvol=/) Where should I look next? I’m on 0.94.6 Thanks in advance, Chris |
