Re: How to properly deal with NEAR FULL OSD

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I changed my volume PGs from 300 to 512 to even out the distribution, right now it is backfilling and remapping and I noticed that it's working.

---
osd.2 is near full at 85%
osd.4 is near full at 85%
osd.5 is near full at 85%
osd.6 is near full at 85%
osd.7 is near full at 86%
osd.8 is near full at 88%
osd.9 is near full at 85%
osd.11 is near full at 85%
osd.12 is near full at 86%
osd.16 is near full at 86%
osd.17 is near full at 85%
osd.20 is near full at 85%
osd.23 is near full at 86%

We will be adding a new node to the cluster after this.

Another question, I'de like to adjust the near full OSD warning from 85% to 90% temporarily. I cant remember the command.
