Volume scan regularly finds large number of errors

Question

I've only had the box for a few days but twice now on reboots I'm getting emails like below. This seems like an awful lot of errors for such a short period of time. Should I be concerned? Normally if I see a lot of fixes like this I also expect to lose a few files. Is that happening here? There has been no power outage or unexpected shutdown. This email was sent after I scheduled a reboot from the web interface. Incidentally the reason I chose to reboot the box is that I had second instance of a locked file giving "Text file busy" error when trying to do anything with it in linux over CIFs mount.

*edit: This is for a readynas nv+ v2.

I have this happening as well with my new Duo v2 / 2 x WD20EARX-00PASB0, both HDD's set up as separate volumes Raid0. Pretty disappointing really, does anybody know if this means there has been file corruption?

cynan · Answer

I just got my Readynas NV+ V2 up and running a week ago. I have 3x 2TB drives setup in an XRAID array (3.6TB volume). A few days ago, I copied about 100GB of files over to the NAS. Today, I made some config changes and rebooted. I decided to do a volume scan on reboot.

Just like the examples posted above, the volume scan encountered about a dozen or so block errors. Everything seems to be working, however. Is this something to be concerned about? Does this usually happen after copying large amounts of data to/from the NAS?

Edit: There have been no power outages or improper shut downs that I know of and the unit is plugged into a UPS.. Also, I think it is unlikely that the drives are faulty as I did low-level formats on all and all 3 passed all available manufacturer-provided integrity tests (short and long tests in Seatools for DOS) just prior to installing them in the NAS. They were also updated to the recommended (by Netgear) firmware.

What do the SMART stats say?

Wish · Answer

I've just done a volume scan for the first time on my NV+ v2 an has come up with 50+ i_blocks errors like the previous posts.
Smart stats for all 4 drives are good, no errors logged.
I am also wondering if this is something to be concerned about?

janforman · Answer

ext3 format don't have any i_blocks issue (after reformatting /dev/c/c).

Under ext4 there's no data corruption while fsck found some Inode with incorrect i_blocks number, but it's strange.
Maybe not dangerous, but not normal.

Mounting ext3 as ext4 with quick fsck working fine too.
