[ceph-users] Re: [EXTERNAL] Re: Renaming a ceph node

Hi all, so I used the rename-bucket option this morning for OSD node renames, and it was a success. Works great even on Luminous. I looked at the swap-bucket command and I felt it was leaning toward real data migration from old OSDs to new OSDs and I was a bit timid because there wasn’t a seco

[ceph-users] Re: ceph noout vs ceph norebalance, which is better for minor maintenance

Hi Dan, I appreciate the quick response. In that case, would something like this be better, or is it overkill!? 1. ceph osd add-noout osd.x #mark out for recovery operations 2. ceph osd add-noin osd.x #prevent rebalancing onto the OSD 3. kubectl -n rook-ceph scale deployment rook-ceph-osd--* --r

[ceph-users] Re: ceph noout vs ceph norebalance, which is better for minor maintenance

Sorry -- Let me rewrite that second paragraph without overloading the term "rebalancing", which I recognize is confusing. ... In your case, where you want to perform a quick firmware update on the drive, you should just use noout. Without noout, the OSD will be marked out after 5 minutes and obj

[ceph-users] Re: ceph noout vs ceph norebalance, which is better for minor maintenance

Hi Will, There are some misconceptions in your mail. 1. "noout" is a flag used to prevent the down -> out transition after an osd is down for several minutes. (Default 5 minutes). 2. "norebalance" is a flag used to prevent objects from being backfilling to a different OSD *if the PG is not degrad

[ceph-users] ceph noout vs ceph norebalance, which is better for minor maintenance

Hi, We have a discussion going on about which is the correct flag to use for some maintenance on an OSD, should it be "noout" or "norebalance"? This was sparked because we need to take an OSD out of service for a short while to upgrade the firmware. One school of thought is: - "ceph norebalanc

Hi Matthew, I can confirm that there is something with kernel 6.0.18-200.fc36 (We have it on our OKD 4 nodes). When we upgraded OKD (Opnshift 4 upstream with Fedora CoreOS 36) to  4.11.0-0.okd-2023-01-14-152430, it upgraded the Kernel 6.0.10-200.fc36 -> 6.0.18-200.fc36. We use Rook-CEPH op

An update on this for the record: To fully solve this I've had to destroy each OSD and create then again, one by one. I could have done it one host at a time but I've preferred to be on the safest side just in case something else went wrong. The values for num_pgmeta_omap (which I don't know
