Hi all,
I think I found a bug in cephfs kernel client.
When I create directory in cephfs and set layout to
ceph.dir.layout="stripe_unit=1073741824 stripe_count=1
object_size=1073741824 pool=somepool"
attepmts to write larger file will cause kernel hung or reboot.
When I'm using cephfs client based on fuse, it works (but now I have
some issues with fuse and concurrent writes too, but it is not this kind
of problem).
I think object_size and stripe_unit 1073741824 is max value, or can I
set it higher?
Default values "stripe_unit=4194304 stripe_count=1 object_size=4194304"
works without problem on write.
My goal was not to split file between osd's each 4MB of its size but
save it in one piece.
With regards
Jan Pekar
