Hardware Errors on Mirrored 750GB Seagate Disk on NV+(4.1.6)

Postby SuperFlyBoy » Mon Feb 20, 2012 6:38 am

Hi All,

I'm running 2 x 750 GB Seagate drives (as originally supplied on the NV+) one of which is exhibiting drive errors.

The NV+ reports current config as under:

Online, X-RAID, 2 disks, 71% of 688 GB used
Firmware: RAIDiator 4.1.6 [1.00a043]

This started when we moved PST files over to the NV+ to have clients access them online.

However, when indexing these PST files (with Lookout), then the NV+ would lock up and now the log is reporting the HD errors. (Only one disk reporting)

The only way to restart the machine was a forced shutdown, so the logs reflect this (Have not opened that Outlook client, due to the fact that it locks up the NV+, which is why there are no problems since the 17 Feb note in the log):

Fri Feb 17 04:00:07 IST 2012 ATA error count has increased in the last day. Disk 2: Previous count: 1656 Current count: 1677 Growing SMART errors indicate a disk that may fail soon. If the errors continue to increase, you should be prepared to replace the disk.

Thu Feb 16 12:44:03 IST 2012 RAID sync finished on volume C. The volume is now fully redundant.

Thu Feb 16 04:00:05 IST 2012 ATA error count has increased in the last day. Disk 2: Previous count: 0 Current count: 1656 Growing SMART errors indicate a disk that may fail soon. If the errors continue to increase, you should be prepared to replace the disk.
Wed Feb 15 21:44:01 IST 2012 System is up.

Wed Feb 15 21:15:03 IST 2012 RAID sync started on volume C.

Wed Feb 15 21:14:22 IST 2012 Improper shutdown detected. To ensure data integrity, a filesystem check should be performed by rebooting the NAS through Frontview with the volume scan option enabled.

Wed Feb 15 16:42:47 IST 2012 System is up.

Wed Feb 15 16:09:07 IST 2012 RAID sync started on volume C.

Wed Feb 15 16:07:37 IST 2012 Improper shutdown detected. To ensure data integrity, a filesystem check should be performed by rebooting the NAS through Frontview with the volume scan option enabled.

Wed Feb 15 14:05:22 IST 2012 A SATA reset has been performed on one or more of your disks that may have affected the RAID parity integrity. It is recommended that you perform a RAID volume resync from the RAID Settings tab ( accessible in the Volumes page => Volume tab in FrontView ). The resync process will run in the background, and you can continue to use the ReadyNAS in the meantime.

Wed Feb 15 14:05:07 IST 2012 Access to the disk on channel (??) is producing I/O errors. Although the array is still redundant, please replace this drive as soon as possible, as it is likely to fail soon.


If we are currently on X-RAID, then I could just slip in another disk and it should become redundant, allowing me to remove the one bad disk - or do I need to add 2 more disks?

However, I just purchased 2 Western Digital 2 GB disks, which this firmware (4.1.6) might not be able to handle, right?

I know I should do a backup before updating firmware, so need to know whether the NV+ would recognize the 2 TB Western Digital Caviar Blacks (WD2002FAEX) as they are?

Thanks for any feedback on this!

WD2002FAEX HDD is compatible with NV+
your 2nd drive seems to be in bad condition,you might need to do these things:
--remove bad disk 2
--power on your device
--hot add a brand new disk once system is up and data is verified
--wait resync job until it is finished
--hot add another one new disk

By default, Xraid mode with 2 disks is actually raid 1 mode,when you hot plug one more disk then it will change to raid 5 mode automatically.

Would I have to format one of the new WD Blacks before placing inside the NV+?

If it mirrors, then only 750 GB (or 688GB) would be used out of the 2 TB?

Also, I'm not sure that 4.1.6 can handle the 2 TB disks, correct? Can anyone confirm?

The NAS will format the disk. Hot-add (add while NAS is on) as suggested.

Yes X-RAID uses the capacity of the smallest disk.

For 2TB disks you should be running RAIDiator 4.1.7 or later.

Also if your 2TB disk is 4k sector you will want to do a backup followed by a factory reset. See Why you might want to factory reset a Sparc ReadyNAS

Can you update the firmware on an NV+ without a disk in place?

Should I remove the failed disk, then update the firmware, as I think the backup will fail in any case, as this PST file appears to be the problem - I was just trying to copy it off the file server and it again locked up the NV+.

Is it because Disk 2 is the one that is failing?

Should I remove Disk 2 and try copying that particular PST file to see if a problem occurs?

Any ideas on which disk is being accessed on the NV+ if they are redundant?

Possible, but last resort to update the firmware.

That is an option

If a disk is failing it can cause all kinds of problems.

Yes.

All of them.

Okay, hot-pulled out the failing disk, second light slot where it was earlier blinking yellow.

Put in the WD2 TB, was recognized, formatted, and now shows x-raid as well, but it is not showing as redundant.

Should I have placed it into the 2nd slot where the Seagate was?

(FIrmware not updated quite yet - wanted a redundant disk first)

Yes, you should have put the replacement disk in the slot where the failed disk was.

Okay, I have another - can I place it in there, or swap Disk 3 (the current WD 2 TB) into Slot 2?

You could try placing your additional 2TB disk in slot 2.

I said to add your extra disk, I think.

Actually what I would recommend you do is ensure you have a good backup, then remove the 2TB disk from the NAS, update to the latest firmware and then do a factory default (http://www.readynas.com/kb/faq/boot/how_do_i_use_the_boot_menu) with just your 2TB disks in the NAS.

Well, just took the other spare WD 2TB disks, put it in an external HD USB enclosure, formatted it with my Win7 laptop, hooked it up to the front USB port, configured a backup job for the C drive and let it rip.

Getting errors like this (also HD enclosure light went red, disk hot):

cp: preserving permissions for '/USB_HDD_1/./Company7/IMAGE (2).PDF': Operation not supported
cp: preserving permissions for '/USB_HDD_1/./Company7/Invoice Nos new.xls': Operation not supported


Therefore, the backup failed.

(Now checking disk (brand-new) for errors on the Win7 laptop - this disk running quite hot, maybe I should use WD Greens instead?)

I took the risk of updating with the one primary 750GB disk and it went successfully.

I cannot say the same about the WD Blacks - they seem to be running *very* hot - especially the one which failed the backup, but a SpeedFan analysis of the drive did not show any problems.

I just reformatted the WD 2TB in Slot3 as it was giving substantial errors with the NV+, and reinstalled it into Slot2, with the new firmware in place.

It is now doing an expandable X-RAID intialization, which is great!

The down aspect of this is that the NV+ probably fried the other WD Black 2TB (brandy-new too!) and this is why it's running hot.

Could be a problem with the USB SATA enclosure?? Shows a date of 2007...

Would WD give me a new drive under their guarantee if it's running hot (but drive is accessible?)
