I’ve successfully used a *temporary* relax of the ratios to get out of a sticky situation, but I must qualify that with an admonition to make SURE that you move them back ASAP.
Note that backfillfull_ratio is enforced to be lower than full_ratio, so depending on how close to the precipice you skate, you may need to raise full_ratio slightly too. And change it back ASAP. I can’t stress that enough. pgremapper might help get out of this too, or depending on how many problematic OSDs you have, surgical manual remaps: https://indico.cern.ch/event/669931/contributions/2742401/attachments/1533434/2401109/upmap.pdf upmap PDF Document · 213 KB > On Nov 6, 2024, at 9:11 AM, Eugen Block <ebl...@nde.ag> wrote: > > Hi, > > depending on the actual size of the PGs and OSDs, it could be sufficient to > temporarily increase the backfillfull_ratio (default 90%) to 91% or 92%, at > 95% is the cluster is considered full, so you need to be really careful with > those ratios.
