NV+

My NV+ has been RESYNCing for 5 days. 
RAIDar still shows 0.0% complete.
Raidiator is almost impossible to use due to sluggishness.

Unit has been power cycled.
Nothing changes.
Backup in Frontview fails on every attempt to backup the array.
Four 2TB WD Red disks.
Set to 3 disk RAID-5 with a spare.
RAID-5 was contained on disks 2-4.
Disk 1 was the spare.
Disk 2 popped out of the device because the clamp failed.

Disk 2 was reconnected, but Frontview still says it is dead.
The resync is active on disks 1, 3, & 4.
But it doesn't appear to actually be happening according to RAIDar.

Any suggestions would be appreciated.

    Additionally, is there anyway to turn off the requirement to log in to these two ReadyNAS devices every 30 minutes or whatever it is?  I'd like to be able to quickly check on the backup status during the day without having to log in constantly.

    The NV+ shouldn't be logging you out.  OS-6 will, and unfortunately there is no way to adjust the timeout.

    This is on the OS-6 NAS?  Is NFS enabled as a file sharing protocol on both NAS?  SMB is called "Windows/NAS (timestamp)" in the backup job setup.

    I'm thinking that disk 4 is the RAID parity disk on the NV+.  If so, the NAS is needing to reconstruct the data that was on disk 2 on the fly.  That will slow down the transfer speed with all protocols (I've never tried to measure how much).  Though you measured 30 MB/s before with SMB, that might not be sustainable.  SMB or NFS would still be faster than rsync though.

     

    How much data is on the NV+?  

     

    The only way to speed it up is to switch to NFS or SMB.  Though now that resyncing is off the table, you could run the backups only during the day (reducing the off-hours power use).  Rsync would need to rebuild the list of files to be transferred every time you restart the backup job, but it wouldn't recopy the already-transferred files (assuming it is set to incremental).

     

    Since the volume is degraded, you do want to transfer the most important shares first.  Also, it would be prudent to minimize writing data (or reorganizing files/folders) on the NV+.

    Welcome to the Community!

     

    It shouldn't take that long, were you able to download the full logs?  If you have kindly check the status.log and check if there are other alerts.

     

    Also, was disk2 reinserted while it is resyncing disk1? Have you tried removing disk 2 and 1 and still get a degraded mode on the array?

     

    Regards

    • Yes, as soon as I discovered that disk 2 had popped out, I pushed it back in.  The NV+ was resyncing to the spare disk 1 when I did that.

      Last night I did a clean shut down from Frontview.  I selected the check file system option.  It has been doing the check file system all day today.  Do you think that this will also get stuck and continue for days?

        The NAS won't do anything with Drive 2 untill the current sync is complete, so that's normal.  But the eternal sync is not.  It's usually a sign that the "new" drive has many bad sectors, but is not 100% dead; though it could be another drive.  Power cycling during the sync was a bad idea, and would cause the sync to re-start; but I think it should have completed already, anyway.

         

        Re-starting with just drives 3 & 4, as suggested by Marc_V is probably the right next step, but it would be best if you could first confirm the status of the array via logs or SSH.
