Hi, I cannot get an answer from user list, so asking to devel list.
I am getting [dht-diskusage.c:277:dht_is_subvol_filled] 0-v0-dht:
inodes on subvolume 'v0-disperse-56' are at (100.00 %), consider
adding more bricks.
message on client logs.My cluster is empty there are only a couple of
GB files for testing. Why this message appear in syslog?
dht uses disk usage information from backend export.
1. What is the out put of du -hs <back-end-export>? Please get this information for each of the brick that are part of disperse.
2. Once you get du information from each brick, the value seen by dht will be based on how cluster/disperse aggregates du info (basically statfs fop).
The reason for 100% disk usage may be,
In case of 1, backend fs might be shared by data other than brick.
In case of 2, some issues with aggregation.
Is is safe to
ignore it?
dht will try not to have data files on the subvol in question (v0-disperse-56). Hence lookup cost will be two hops for files hashing to disperse-56 (note that other fops like read/write/open still have the cost of single hop and dont suffer from this penalty). Other than that there is no significant harm unless disperse-56 is really running out of space.
