Hi all,
with the option "cluster.min-free-disk" set, glusterfs avoids placing files
bricks that are "too full".
I'd like to understand when the free space on the bricks is calculated. It
seems to me that this does not happen for every write call (naturally) but at
some interval or that some other event triggers this.
i.e, if I write two files quickly (that together would fill a brick) I'd get a
error message:
dd if=/dev/zero of=a bs=1k count=15000 && sleep 1 && dd if=/dev/zero of=aa
bs=1k count=15000
#yiels: dd: error writing ‘aa’: No space left on device
#(brick1 is full, but glusterd still tries to place file "aa" on the same brick
dd if=/dev/zero of=a bs=1k count=15000 && sleep 60 && dd if=/dev/zero
of=aa bs=1k count=15000
#this works....
#link file on brick1 to "aa" and the real "aa"-file on brick2
when is statfs (or a simlar call) evaluated?
Thank you!
best wishes,
Stefan
