This test is still being skipped for ZFS. A patch needs to be submitted to remove it from ALWAYS_EXCEPT, with Test-Parameters: sanity-quota ostfilesystemtype=zfs run enough times that we are confident that it is passing consistently.

Old blocker for unsupported version

[Andreas Dilger]

Bug was closed, but sanity-quota test_3 and test_6 are still being skipped for ZFS filesystems

[Peter Jones]

Landed for 2.4

This one is for ldiskfs, it's little bit different with other failures for zfs.

This is a slow dd command, which is related other slow dd commands.

When approaching quota limit, client turns to sync write (one page by one page), on some slow test system, data flush could take very long time (longer than grace time), then grace could expires before we start testing.

I think we'd enlarge the grace time for the test_3.

LU-2837 has the similar problem, we'd enlarge the waiting time for test_6 either.
