I've checked statedump of volume in question and haven't found lots of
iobuf as mentioned in that bugreport.
However, I've noticed that there are lots of LRU records like this:
In fact, there are 16383 of them. I've checked "gluster volume set help"
in order to find something LRU-related and have found this:
Default Value: 16384
Description: Specifies the maximum megabytes of memory to be used in the
Is there error in description stating "maximum megabytes of memory"?
Shouldn't it mean "maximum amount of LRU records"? If no, is that true,
that inode cache could grow up to 16 GiB for client, and one must lower
Another thought: we've enabled write-behind, and the default
write-behind-window-size value is 1 MiB. So, one may conclude that with
lots of small files written, write-behind buffer could grow up to
inode-lru-limit×write-behind-window-size=16 GiB? Who could explain that
