Help! RAID5 unmounted - I haven't backup:(

Post by zhou01 »

Hi Friends,

I couldn’t mount my TS-412 anymore. Unfortunately I haven’t backup and will lost my all files since 20 years. Please advise me what I should do?

By mount:

[~] # mount /dev/md0 /share/MD0_DATA -t ext4
mount: wrong fs type, bad option, bad superblock on /dev/md0,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

did that happen by itself or did you have a power outage/lightning storm/etc ?

The raid5 itself looks ok, and this old CAT1 unit does not have any LVM structure on top of it

Open a support ticket with QNAP. Also, those Seagate DM HDDs are a problem waiting to happen. Best to replace those. Lastly, start doing external backups.

i don't know how much storage you are using, but a wd elements or easystore external storage (whichever you can get cheapest on a deal) might be the way to go.

hi zhou01,

did you ever had a chance to get your raid 5 working again? I have the same problem - had a power outage and now my raid5 md0 can't be mounted - same failure messages?
