Hi all,
It seems that the CI setup has changed, and /var/tmp is using now tempfs.
This is not compatible with vdsm tests, assuming that /var/tmp is a real file
system. This is the reason we do not use /tmp.
We have lot of storage tests using directio, and directio cannot work on
tempfs.
Please check the slaves and make sure /var/tmp is using file system supporting
directio.
See example failure bellow.
