Hi all,
short question about my zpool. (long story, short question)
My main Desktop PC uses 2 HDDs with ZFS in mirror.
Yesterday my system completely crashed totally - something went wrong while installation of Guest Additions within VirtualBox (Win7), I don't really know why yet.
However: Total system's crash. Black screens, no reactions to nothing - dead... brute force: hardware reset button (Yep, Ouch!)
After that: loooooong BIOS hardware check (I was really worried, my hardware was gone..if you just see a blinking cursor on a black screen only over endless minutes, no BIOS starts...),
again loooong time BIOS needed to detach all drives (had problem to determine one HDD, the one concerned)
Life teached me, sometimes is best just to be patient, wait and trust.
After a while: Voilá, FreeBSD bootloader (phew!), long boot, system up again - big relief!
zpool status "degraded" - one of my two HDDs was shown as blank, unformatted, not implemented (long number, no partition "formerly ada1p3, remove from pool,...exchange!"
After a couple of minutes (checked if at least all arms and legs are still attached where they belong to) reboot - commonly, not with the hammer by pulling the plug :-D
zpool status already "degraded" and "replace disk", but disk (partiton) is already in the pool as ada1p3, shown as before the crash, except Checksum Error 36.
So I scrubbed the pool, nothing changed except now it was cheksum 60.
Knowing to have to replace the disk first thing this morning, I started my computer...checked some emails... let's repair the pool...
Of course, the very first thing before I start anything with my pools is
...everything is shown as nothing has happened at all:
Also gpart shows me, that everything is normal again.
So, no damages so far as stated by system tools.
Right?
Is really everything alright again, now?
Can I trust this?
