[ceph-users] CRC mismatch detection on read (XFS OSD)

Hi! Just found strange thing while testing deep-scrub on 10.2.7. 1. Stop OSD 2. Change primary copy's contents (using vi) 3. Start OSD Then 'rados get' returns "No such file or directory". No error messages seen in OSD log, cluster status "HEALTH_OK". 4. ceph pg repair Then 'rados get' works

Re: [ceph-users] How's cephfs going?

Hi, I can share negative test results (on Jewel 10.2.6). All tests were performed while actively writing to CephFS from single client (about 1300 MB/sec). Cluster consists of 8 nodes, 8 OSD each (2 SSD for journals and metadata, 6 HDD RAID6 for data), MON/MDS are on dedicated nodes. 2 MDS at al

Hello! It is clear what happens after OSD goes OUT - PGs are backfilled to other OSDs and PGs whose primary copies were on lost OSD gets new primary OSDs. But when OSD returns back it looks like all that data, for which the OSD was holding primary copies, are read from that OSD and re-written t

Re: [ceph-users] 2x replication: A BIG warning

Hi, Let me add a little math to your warning: with LSE rate of 1 in 10^15 on modern 8 TB disks there is 5,8% chance to hit LSE during recovery of 8 TB disk. So, every 18th recovery will probably fail. Similarly to RAID6 (two parity disks) size=3 mitigates the problem. By the way - why it is a c

[ceph-users] rados bench leaves objects in tiered pool

Hi, While benchmarking tiered pool using rados bench it was noticed that objects are not being removed after test. Test was performed using "rados -p rbd bench 3600 write". The pool is not used by anything else. Just before end of test: POOLS: NAME ID USED %U
