Hello,
I have a qnap TS230 with two disks in raid 1 and thin volume.
One day it stopped working. I tried booting without disks to recover control.
Now I see one disk broken but the other one is ok.
I try to check volume and it stops after few seconds.
I have tried to mount the disk with linux but I get this error that seems related to proprietary extensions:
LV vg1/tp1, segment 1 invalid: does not support flag ERROR_WHEN_FULL. for tier-thin-pool segment.
Internal error: LV segments corrupted in tp1.
Now what can I do?
I do not understand why, with a raid1 array, losing one drive means losing all data.
Nas did not boot anymore. I followed a guide that told me to boot without hard disks. It booted.
Then I added disk and it offered me three prompts:
reboot from disks
reset configuration but not delete disk contents
delete disks
I have chosen 1 but it did not work.
I have chosen 2 and it booted.
Then I was able to see that one drive was broken.
But even the good one was not mounting the thin volume with all the data.
The file system check stops after few seconds.
Can someone explains me whats happened?
Why I buy two disks if it not useful at all?
Thanks,
Mario
PS: regarding backups, the QNAP was THE backup and I correctly added a raid1 to be sure to not lose my backups
Unclear what happened on your NAS…best to open a ticket and have them investigate.
If your NAS was the backup, no harm done. You can always recreate the data from the source then. If not, then the NAS was NOT a backup (just calling something a backup, does not make it one)
Well, you can’t rely in JUST the NAS to be your backup. Backups should be done in multiple places in multiple ways. Hardware failure happen. Disk drives fail, etc.
Again…just calling something a backup, but not using it as such,is not the NAS fault.
Many people buy a USB Backup disk…they call it a backup, but they actually EXCLUSIVELY keep the files on it. When this drive then dies…sooo many tears, but they had a backup (no, they did not)
Sadly, I’ve learned this lesson too late and after multiple “losses.”
I have work and files from years ago that are gone. I have had many drives fail over the years. I hold on to them hoping that the drive will suddenly work again. Then I started relying on backups using TimeMachine on my Mac and an Apple AIrPort TimeCapsule. Had at least one Time Capsule fail on me. Not sure I really lost much but lost all my backup history. My latest TimeCapsule has failed again as it got knocked off where it was sitting and fell. The drive just clicks now.
Had a MacPro from about 15 years ago where I had a 3TB drive created by RAID0. Guess what - a drive failed even though it was new. I set the machine aside for years figuring the data was “safe” and I’d resurrect it. Just recently tried to get my data back. Gone. One of the drives was recognized by my current Mac as being part of a RAID. The other drive - never even spun up. Then the first drive started dying (hard drives seem to die if they are not used).
Then I started trusting online stuff like iCloud as Apple certainly backs up their servers. Then I started seeing weird things happening with iCloud and files disappearing. That’s when I got serious with backups and my QNAP. I have lost stuff that I can never get back and while I could have sent it to a recovery place, I am not sure that the thousands of dollars I would have paid would have been worth it.
Now I do hourly TimeMachine backups to two different QNAP NAS units. I backup the data on my main NAS to my secondary NAS. I backup my main NAS to iDrive. I backup critical files on my NAS to myQNAPCloud drive space. I do snapshots and I do snapshot vaults between the NAS units.
I’ve become fastidious and maybe too much about backups. But having “one” backup is certainly not enough. The more places you have it and the more different formats, the better it is especially with ransomeware attacks, etc.
I always have thought it odd that large businesses get these ransomeware attacks and are crippled but they have apparently no backups or one backup with infected data. I never applied that same reasoning to myself. Now I do.
I repeat for the last time.
I had my backups on that nas. Another copy on internet. Actually no new backups are made because I have not my nas working.
If you are so aggressive telling that is my fault (but I have no fault…) I begin to suspect you want to hide the fact that really happened: one disk broke and I lost an entire nas with a raid1. This is a serious thing that cannot be covered telling me that I am stupid because I had to do backups. I have infact backups but my money are important and I will not spend them in broken devices.
