rn214not expanding

i have a readynas 214 with 1x 4tb an thd 3 x 3tb hoever the capacity is coming outon  the admin page as 6.35 tb i think i should be getting in the region of 7.4tb based on the readynas calculator giving 8.26tiB x 0.9095 conversion  tiB to TB although thes um of all srives lesslargest = 9 is that the correct raid 5 calculation for array capacity?

 

eith eay f its not expandibg correctly how can i fix? ideally without having to delet the volume and recreating then restoring backup. as the backup does not include my time machine bckups

the

tia

Re: rn214not expanding

And XRAID is enabled?

 

A TB is smaller than a TiB, so you did the conversion wrong.  You should be getting 8.16TiB.  But I think the NAS thinks you still have two 2TB drives and either two 3TB or one 3TB and one 4TB (because the extra 1TB of 4 would currently be unused).  That indicates that the expansion problem occurred before you made your latest disk swap.

 

If you post the contents of mdstat.log from the downloaded log .zip file (using the </> "code" tool in the forum works best) and describe the starting drive configuratrion and what changes have been made along the way, we may be able to see if there is a way to fix it.

Re: rn214not expanding

Did you just replace the disk?  If so, you just needed to wait longer (likely it is already expanding by now).

 

Also, what disk models do you have?

 

 

 

This is the original RAID group, which is still resyncing (which looks like you just replaced a disk).

 

md127 : active raid5 sda3[6] sdd3[4] sdc3[5] sdb3[1]
      2915738496 blocks super 1.2 level 5, 64k chunk, algorithm 2 [4/4] [UUUU]
      [==================>..]  resync = 90.5% (880496640/971912832) finish=46.4min speed=32810K/sec

 

 

After this completes, the expansion step will begin.

Re: rn214not expanding

according to the admin pgsges is stopped resyncing  a good few days ago it has  ximpleted the resync without moving onto expansion it would seem

 

drive models are:

What is the current mdstat?

  • wdc wd40efax-6h 68jh4n0

I was wondering about that.  That is an SMR drive, which is not well suited for RAID.  I have no idea what WDC was thinking when they used that technology in a NAS-purposed drive.  The newer "WD Red Plus" line has the WD40EFRX, which doesn't have that problem.

Re: rn214not expanding

so sounds like if i reoplace the 1st drive the wd smar drive i might be able to use full capacity what is the conflict between smr and raid?

Look here:  https://www.servethehome.com/wd-red-smr-vs-cmr-tested-avoid-red-smr/2/

 

Note particularly the section that says:

Unfortunately, while the SMR WD Red performed respectably in the previous benchmarks, the RAIDZ resilver test proved to be another matter entirely. While all three CMR drives comfortably completed the resilver in under 17 hours, the SMR drive took nearly 230 hours to perform an identical task.

 

The RAIDZ resilver operation is similar to what your NAS does with a resync and vertical expansion.

I think the next step is to re-download the log zip file, and see what the current status of the mdstat.log is.  I understand that the web ui might show the resync as completed, but I think it makes sense to look more closely in the logs.

The resync has completed.  Your array has 2 RAID groups (shown above).. 

 

The problem is that md126 is missing one of the disks (sdc).

 

Can you also look in disk_info.log at sdc?  It'd be useful to know what disk it is (and double-check the size).

Re: rn214not expanding

if  i deleted the volume and created a new one and restored data from a backup would i be sure to get the full capacity expected? or am i looking for a needle in a haystack trying to work this out?

Message 13 of 25

Re: rn214not expanding

The space you are missing is on disk 3 (sdc).

 

Perhaps remove disk 3, and then reformat it (or unformat it) in a Windows PC.  Then reinsert it, and see if after resync you get the full space.  If you reformat it in Windows then you'll need to reformat it again in the NAS.

 

Definitely make sure your backup is up to date first though.

Re: rn214not expanding

i only have a msc so will only be able to format it using disk utility any particular format type i.e fat32 macos extended etc? is it possible to format that individual drive in the nas itself?

What is an msc?

 

The format used in the PC actually doesn't matter - the point is really to remove the NAS formatting, and then have the NAS reformat it again.  Unformatting (for instance with the windows disk manager), or zeroing the disk (using a number of utilities) will work just as well.

 

You'll need to remove the disk from the NAS though, as it won't let you remove the disk from the array.

Re: rn214not expanding

Typically, just removing any partitioning with a PC is sufficient, especially removing any system reserved partition since the NAS can't handle them (can't even delete them).

Yes.  Unformattng the drive (removing the partitions) will make the NAS think it's a new drive.

 

So will zeroing the drive with vendor tools (seatools or lifeguard), or other low-level tools.

Re: rn214not expanding

Maybe try powering down the NAS, and removing the existing disks (labeling by slot).

 

Then try powering up with the disk in slot 1 (other slots empty), and see if it is recognized.  You'll need to do a factory default procedure from the boot menu.

The idea is to first double-check that the NAS can detect the disk (the original disk 3) in any slot.  So start with slot 1, and do a factory default - that should install the OS on the disk, and create a jbod volume. If it works, then power down, move the disk to slot 2 and reboot.  Continue until you've tested all 4 slots.

 

Assuming the disk is detected and will boot from any slot, then the next step is to try again.  You'd remove the disk, and power up with all the other disks in their correct places.  The system should boot, though the RAID system might say that it's degraded.

 

Then connect the problem disk to your mac and format it again.  Hot insert it into the NAS (while it is running).  The disk should appear on the volume page.  If you select it, you should be able to format it.  If XRAID is on, then it should be immediately added back into the array.

i've taken the nuclear option of filling the unit with all drives i have available and doing a factory default now restoring data  from backup the  volume ca[acity is 8.17 tb with 1x4 3x3 drives better than i had for sure and at least i'm now usingall  my disks that are otherwise unused
