zfs discuss - Jun 2012 - Persistent errors?

Hello

It seems as though every time I scrub my mirror I get a few megabytes of
checksum errors on one disk (luckily corrected by the other). Is there some way
of tracking down a problem which might be persistent?

I wonder if it''s anything to do with these messages which are
constantly appearing on the console:

Jun 17 12:06:18 sunny scsi: [ID 107833 kern.warning] WARNING: /pci at
0,0/pci1000,8000 at 16/sd at 0,0 (sd2):
Jun 17 12:06:18 sunny   SYNCHRONIZE CACHE command failed (5)

I''ve no idea what they are about (this is on Solaris 11 btw).

Check iostat -en or iostat -En <devname>. If the latter shows media
errors, the drive is dying, and should be replaced.

No idea, sorry?

Vennlige hilsener / Best regards

I all pedagogikk er det essensielt at pensum presenteres intelligibelt. Det er
et element?rt imperativ for alle pedagoger ? unng? eksessiv anvendelse av
idiomer med xenotyp etymologi. I de fleste tilfeller eksisterer adekvate og
relevante synonymer p? norsk.

Check the output of ''fmdump -eV'', it should have some (rather
extensive) information.
