[ceph-users] 14. 2.15: Question to collection_list_legacy osd bug fixed in 14.2.15

Hello, I am running a productive ceph cluster with Nautilus 14.2.13. All OSDs are bluestore and were created with a ceph version prior to 14.2.12. What I would like to know is how urgent I should consider the collection_list_legacy bug since at the moment I am not going to add a brand new OSD

[ceph-users] osd crash: Caught signal (Aborted) thread_name:tp_osd_tp

Hello, Three OSD daemons crash at the same time while processing the same object located in an rbd ec4+2 pool leaving a placement group in inactive down state. Soon after I start the osd daemons back up they crash again choking on the same object.

[ceph-users] Cephfs snapshots and previous version

Today I played with a samba gateway and cephfs. I couldn’t get previous versions displayed on a windows client and found very little info on the net how to accomplish this. It seems that I need a vfs module called ceph_snapshots. It’s not included in the latest samba version on Centos 8. by

[ceph-users] Unable to find further optimization, or distribution is already perfect

Hi We're having problems getting our erasure coded ec82pool to upmap balance. "ceph version 14.2.11 (f7fdb2f52131f54b891a2ec99d8205561242cdaf) nautilus (stable)": 554 The pool consists of 20 nodes in 10 racks, each rack containing a pair of nodes 1@45*8TB drives and 1@10*16TB.

[ceph-users] PGs undersized for no reason?

Hi all, I'm upgrading ceph mimic 13.2.8 to 13.2.10 and make a strange observation. When restarting OSDs on the new version, the PGs come back as undersized. They are missing 1 OSD and I get a lot of objects degraded/misplaced. I have only the noout flag set. Can anyone help me out why the PGs

[ceph-users] Re: ssd suggestion

Those are QLC, with low durability. They may work okay for your use case if you keep an eye on lifetime, esp if your writes tend to sequential. Random writes will eat them more quickly, as will of course EC. Remember that recovery and balancing contribute to writes, and ask Micron for the

[ceph-users] ssd suggestion

Hi, We are going to replace our spinning SATA 4GB filestore disks with new 4GB SSD bluestore disks. Our cluster is reading far more than writing. Comparing options, I found the interesting and cheap Micron 5210 ION 3,84TB SSDs. The way we understand it, there is a performance hit, when it

[ceph-users] Sizing radosgw and monitor

Hi, I haven't really find any documentation about how to size radosgw. One redhat doc says we need to decide the ratio like 1:50 or 1:100 osd / rgw. I had an issue earlier where I had a user who source loadbalanced so always went to the same radosgateway and 1 time just maxed out. So the

[ceph-users] Re: NoSuchKey on key that is visible in s3 list/radosgw bk

Hi Denis, You might want to look at rgw_gc_obj_min_wait from [1] and try increasing the default value of 7200s (2 hours) to whatever suits your need < 2^64. Just remind that at some point you'll have to get these objects processed by the gc. Or manually through the API [2]. One thing that
