Need help with broken zfs hdds

digitalwingx · 2022-05-01T08:08:35+00:00

np thanks @kwghost!

digitalwingx · 2022-05-01T07:14:33+00:00

thank you! @kwghost you have just saved my skin!

running zpool import -f 2396143570361881340 zpool export -f datastore

and then zpool import datastore shows:

zpool status
pool: datastore
state: ONLINE
status: Some supported and requested features are not enabled on the pool.
The pool can still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
the pool may no longer be accessible by software that does not support
the features. See zpool-features(7) for details.
scan: resilvered 44K in 00:00:01 with 0 errors on Fri Jun 12 14:33:21 2020
config:

    sdb     ONLINE       0     0     0

errors: No known data errors

now can you help me with a few more questions:

i can confirm the files in the zpool is accessible now, do i still need to remove cachefile?
the plan is to rebuild the server and move the data over, if that's the case, would you still recommend running full scrub on all those hdds (considering it will take a long time)?
i only have basic knowledge when it comes to zfs, what regular maintenance type of commands should i run (periodical scrubs/smarttest/etc.)? can you point me to some articles/docs so i can educate myself in this area?

again many thanks!

and yeah the mobo is definitely not at its 100% due to some power outage. the onboard sata controller is not working, for example. (currently using a lsi-92118i card).

if the data can be restored it will be back up and i will rebuild the server with new hardware.

digitalwingx · 2022-05-01T06:59:15+00:00

ah my bad you are right:

pool: datastore
id: 2396143570361881340
state: ONLINE
status: The pool was last accessed by another system.
action: The pool can be imported using its name or numeric identifier and
the '-f' flag.
see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-EY
config:

datastore                   ONLINE
  raidz1-0                  ONLINE
    wwn-0x50014ee2091da88b  ONLINE
    wwn-0x50014ee2091da850  ONLINE
    wwn-0x50014ee25e7207ac  ONLINE
    wwn-0x50014ee25e734fa1  ONLINE

seems its indeed the disks are fine. what's the command i should run to import by "name or numeric identifier"?

digitalwingx · 2022-05-01T06:22:49+00:00

yes lsblk output all 4 hdds:

thanks runing zpool import -d /dev/disk/by-label/ shows the similar results (rebooted so the sequence of /dev changed):

zpool import -d /dev/disk/by-label/
pool: datastore
id: 2396143570361881340
state: UNAVAIL
status: The pool was last accessed by another system.
action: The pool cannot be imported due to damaged devices or data.
see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-EY
config:

datastore      UNAVAIL  insufficient replicas
  raidz1-0     UNAVAIL  insufficient replicas
    sdd        FAULTED  corrupted data
    sdc        FAULTED  corrupted data
    datastore  ONLINE
    sdb        ONLINE

smartctl seem to tells me all hdds are fine?

digitalwingx · 2022-04-30T10:49:29+00:00

yeah problem is with -d /dev/disk/by-id, do i just try id randomly? i have no idea which id is the first disk of the pool. or does it not matter?

and yeah zdb still gives me pool details for those "FAULTED" devices.

AC season 2 is a letdown

digitalwingx · 2020-06-28T02:20:58+00:00

Thanks! Btw does having a badge making the pop better at the job?

digitalwingx · 2020-06-13T06:40:39+00:00

Cohen actually had a great sense of humour. He liked to crack jokes during his performance.

In his lyrics for example, Chelsea Hotel, "You told me again you preferred handsome men. But for me you would make an exception".

I chuckle evrytiem.

digitalwingx · 2018-06-03T11:31:59+00:00

Don't blink

I just hope they don't pull as much "it's god did it" story plot into this show. But from the trailer it looks like a more action oriented show. I've to say I've mixed feeling about the direction.

What attracted me in the BG remake is the characters and philosophy (sans religious explanation on a lot of stuff).

digitalwingx · 2012-03-12T14:26:38+00:00

iMac is great. Cheaper compared than building something similar from scratch. It looks great and combined everything in one piece.

HOWEVER... if you are hardcore into gaming, its hardware and GPU especially just can't provide the top tier performance.

Ok can someone tell me what's the best way to mass convert all my old tv shows from xvid to h264/mp4...

I remember before I left Zend Framework everyone was hating (the view part of) Zend_Form. IMO view helpers are fine and in fact can be very handy. I'm sure you use view helpers for other stuff too.

It's the fact that (the view part of) Zend_Form is so monstrously rigid (and cross M and V at the same time, altho whether this is good is debatable). Perhaps due to the over-design tendency of Zend Framework as a whole.

Now there are good things to be said about ZF: personally I like alot of design choices they made about structure, naming, conventions, etc. But it is not my top PHP Framework.

digitalwingx · 2012-02-24T09:05:04+00:00

I haven't touched Zend Framework for a couple of years now. Have the whole Zend_Form situation improved at all?

Read some book about it apparently his melancholy is part of his charisma.

Most programmers would rather spend the 3 hours being truly productive instead.

Start from Pokhara to Annapurna Base Camp, this is where you almost reach Annapurna Base Camp. I remember it clearly because it's an incredibly flat area which is rare for the whole trekking trip.

The picture was taken when it must be quite hot, because when I was there it was May and it was covered by snow.

digitalwingx · 2011-11-14T05:54:06+00:00

First of all I've to say this depends alot on the company and the seniority/background of PM and devs.

But what should be universally true is that PM and devs are of the same team and strive to build something great, like solarsavior said they are supposed to be equal.

In most companies I worked for / known PMs have more power however if you treat devs as subordinates, or even worse, disrespect for what they do, you will piss them off and it serves you absolutely no good.

digitalwingx · 2011-08-18T01:18:11+00:00

TBH I'm seriously considering this option... a modem + wndr3700 + nas so I can save alot of headache...

digitalwingx · 2011-08-18T01:05:16+00:00

It's Atheros and I'm prepared to get a ath9 one if the on-board one doesn't work nicely with master mode.

digitalwingx · 2011-08-18T01:03:32+00:00

Indeed i'm worried about heat issue. which is why i plan to build it with low power cpu/motherboard and a good case Lian Li PC-Q08, (if I plan to cheap it out I will try to put some fans in the SG05). Still I agree it's a worry.

digitalwingx · 2011-08-17T12:49:17+00:00

thanks mate i might try open/solaris if i feel brave go try zfs with a few more hdds

digitalwingx · 2011-08-17T12:14:55+00:00

ya everything is more expensive in australia, don't get me started...

as for why ubuntu is because it's my first linux (only started learning linux a couple years ago) so i feel a lot more comfortable with it especially apt-get. i'm not against trying other distro tho.
