In other words your flight reservation will not be lost if the system
crashes.

Consistency means that fsync() assures that the data will be written
to disk so no data is lost. It is not

Hello,
If you believe that the problem can be related to ZIL code, you can try to
disable it to debug (isolate) the problem. If it is not a fileserver (NFS),
disabling the zil should not impact consistency.

I don't think that this is hardware issue, however i don't except this. I'll
try to explain why.
1. I've replaced all memory modules which are more likely to cause such a
problem.
2. There are many different applications running on that server (Apache,
PostgreSQL, etc.). However, if you look a

Lots of CKSUM errors like you see is often indicative of bad hardware. Run
memtest for 24-48 hours.

included a number of fixes to AHCI SATA driver and ZFS.
Didn't help

Seems kind of old. I am using Generic_127112-11 here.
Probably many hundreds of nasty bugs have been eliminated since the
version you are using.

Today my production server crashed 4 times. THIS IS NIGHTMARE!
Self-healing file system?! For me ZFS is SELF-KILLING filesystem.
I cannot fsck it, there's no such tool.
I cannot scrub it, it crashes 30-40 minutes after scrub starts.
I cannot use it, it crashes a number of times every day! And wi
