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

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 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!

- To use disks greater than 2TB in capacity you'd need a new NAS.
However what I'm saying is that you should backup your data and do a factory reset to get 4k sector partition alignment. That way you don't have to worry which 2TB disks you purchase so long as they're on the compatibility list. If a disk fails you again just have to look for one on the compatibility list to replace it. mdgm wrote: To use disks greater than 2TB in capacity you'd need a new NAS.

Right - understood.
I'm not sure I have the time to do the reset on the NV+ at this time - I think I am looking at a NAS which can backup to CrashPlan - which this one definitely cannot do, so then the extra effort is moot.- Could still use this NAS as a backup NAS. Once you've migrated your data to a new NAS, update to 4.1.7 or later and do a factory default and then use the NV+ for a local backup of important data.
x86 ReadyNAS e.g. Ultra, Pro can be used with Crashplan though you'd need to enable SSH access to install it etc. mdgm wrote: Could still use this NAS as a backup NAS.

Right - this unit is on 4.1.8 at present.
We will see how things progress - no funds to invest in another at this time...these hard drives are pretty expensive over here.- Well if you can't do the reset and can't get a new NAS, make sure NOT to buy drives that are 4k sector (advanced format). Make sure you buy 2TB drives that are 512-byte drives.
I agree that it is easier/more convenient to have 4K alignment. Otherwise you have to research each 2 TB drive purchase, and the new format is already becoming mainstream on new drive models. Also (assuming this is inevitable/in your future anyway) it is much better to rebuild the array when you know the disks are good.mdgm wrote: ...

CrashPlan is good, esp. for disaster recovery. However, it is not as fast as local backup. Also, the Crashplan folks do not recommend using only one backup site. So I use my older duo/NV+ units to backup my pro, which is also (very recently) being backed up with crashplan.SuperFlyBoy wrote: I'm not sure I have the time to do the reset on the NV+ at this time - I think I am looking at a NAS which can backup to CrashPlan - which this one definitely cannot do, so then the extra effort is moot.
BTW, with some effort it might be possible to use a PC with Crashplan to backup the NV+ (mapping the shares as a network drive). CrashPlan does not officially support this, but they do provide a guide here: http://support.crashplan.com/doku.php/r ... ped_drives. I haven't tried it myself though.StephenB wrote: BTW, with some effort it might be possible to use a PC with Crashplan to backup the NV+ (mapping the shares as a network drive).

Yes, I'm doing something similar with LiveKive (AVG) for one of the directories that are most important.
Will try to look at your link when I have time - thanks for that!- Now I have 3 x 2 TB WD disks installed as under:
RAID Disks:
Ch 1 : WDC WD2002FAEX-007BA0 [1862 GB] 694 GB allocated
Ch 2 : WDC WD2002FAEX-007BA0 [1862 GB] 694 GB allocated
Ch 3 : WDC WD2002FAEX-007BA0 [1862 GB] 694 GB allocated
However, how do I ramp them up to their full capacity of 1862 GB - a hard reset after backup - is this the only way? - What is the volume status? Is it redundant?
If so, have you tried a reboot? mdgm wrote: What is the volume status? Is it redundant?
Yes, it's redundant now.mdgm wrote: If so, have you tried a reboot?
Not after installing the third disk in the original position (Slot 1) of the 750 GB Seagate - the one that wasn't failing.
That one is now removed, in case it also starts to act up and because posts here mentioned (or as I understood) that it might limit the capacity of the other 2 TB drives...
Do slot positions even matter?
