Hi All. Nautilus 14.2.8. I came in this morning to find that six of my eight NVME OSD's that were housing the cephfs_metadata pool had mysteriously filled up and crashed overnight and they won't come back up. These OSD's are all single logical volume devices with no separate WAL or DB. I have tried extending the LV of one of the OSD's but it can't make use of it and I have added a separate db volume but that didn't help. In the meantime I have told the cluster to move cephfs_metadata back to HDD which it has kindly done and emptied my two live OSD's but I am left with 10 pgs inactive. BLUEFS_SPILLOVER BlueFS spillover detected on 6 OSD(s) osd.93 spilled over 521 MiB metadata from 'db' device (26 GiB used of 50 GiB) to slow device osd.95 spilled over 456 MiB metadata from 'db' device (26 GiB used of 50 GiB) to slow device osd.100 spilled over 2.1 GiB metadata from 'db' device (26 GiB used of 50 GiB) to slow device osd.107 spilled over 782 MiB metadata from 'db' device (26 GiB used of 50 GiB) to slow device osd.112 spilled over 1.3 GiB metadata from 'db' device (27 GiB used of 50 GiB) to slow device osd.115 spilled over 1.4 GiB metadata from 'db' device (27 GiB used of 50 GiB) to slow device PG_AVAILABILITY Reduced data availability: 10 pgs inactive, 10 pgs down pg 2.4e is down, acting [60,6,120] pg 2.60 is down, acting [105,132,15] pg 2.61 is down, acting [8,13,112] pg 2.72 is down, acting [93,112,0] pg 2.9f is down, acting [117,1,35] pg 2.b9 is down, acting [95,25,6] pg 2.c3 is down, acting [97,139,5] pg 2.c6 is down, acting [95,7,127] pg 2.d1 is down, acting [36,107,17] pg 2.f4 is down, acting [23,117,138] Can I backup and recreate an OSD on a larger volume? Can I remove a good pg from an offline OSD to remove some space? Ceph-bluestore-tool repair fails. "bluefs enospc" seems to be the critical error. So currently my cephfs is unavailable so any help would be greatly appreciated.
