If the device on the secondary node does not supports DELETE, but the
device on the primary does, HAST will report to ZFS that DELETE
succeeded (although it failed on the secondary), and ZFS will not
disable TRIM. Pete, isn't this your case?
Afraid not, both machines are running normal "spinning rust" hard
drives as the actual storage layer, so there is nothing TRIM capable
anywhere.
I didnt get much chnace to look at this yesterday, but am looking at the logs
again now, and I see these messages right up to the time the machine
fell over. That machine had been up for a long time, and it was still logging
these messages, so it looks very much as if ZFS did not stop trying to
issue the TRIM.
What do you see from:
sysctl kstat.zfs.misc.zio_trim
You should be seeing none zero unsupported and zero failed. If this is
not the case its likely hast isnt setting bio_error to ENOTSUP.

Steve
