Hello and thanx for your replyTo reiterate, this is normal recovery for a failure in raid mirroring. This is a raid function, you can "blame" QNAP if you wish, but it is basic Linux code, nothing to do with them really.
I agree, it has something to do with the Raid application and/or the ext4 partition. But if it's the Raid application, it's something QNAP chose and configured.
As I said, I have a DLink and a WD running Raid1 partitions, and a Sheevaplug/Debian with a single disk ext4 partition. They went down the same way the QNAP did, and I never had those problems with them. And never had those problems with the servers I monitor at work but those are of course using Raid hardware
sorry, missed the post where you asked for those infos.I'll also ask again what HDD Manufacturer and model you are running along with the approximate age of the drives.
I'm at work right now, so I'll give you more infos when I get home. But the disks are Seagates. And they are not that old, and haven't been on that long. I have older disks of course with no pb whatsoever.
The SMART values are the ones that QNAP gave me using the GUI. I'll have to ssh the NAS to see if I can get more information. Dunno what smart application is being used. If it's smartmontool then I'll check the logs. Otherwise, gonna have to look deeper.
Will tell you when I get homeIt isn't the QNAP uptime I was asking about, it is the runtime of the HDDs.
SMART 9 power-on_hours.
How about 1 raw_read_error_rate and 7 seek_error_rate?
The tests I ran are from the QNAP GUI , they don't report detailed stuff. But I would assume that if there were bad sectors, it would report them... Otherwise, what's the point?No, not necessarily. If the HDD self-corrected, then your tests would NOT show this. It would be buried in the SMART data.
I have both a TS-563 and a TS-231P (the later is pretty similar to yours). In all fairness, this is primarily a router forum. Have you tried posting on the QNAP community forum https://forum.qnap.com/ or entering a help ticket with QNAP directly? (I strongly suspect that they will tell you the same things we are though).
It's an old NAS, out of warranty. I don't think QNAP would help me there.
Maybe the QNAP community indeed. I'll try that too, thanx for the tip
