[drive in parity is not the biggest]

hi

i shucked a wd elements 8tb into my array and now i am getting the error that the parity drive hast to be the biggest.

my current setup is:

 

data: 6 disk (4-8tb wd reds)

parity: 1 disk (8tb wd red)

 

i want to add the shucked drive as a data disk but get the error about parity not being the biggest disk.

sector counts on the disks are identical

 

what gives?

 

EDIT: nvm the partition on the shucked drive is slightly smaller than the parity ( 7.814.025.540 vs 7.814.026.532)

shameless bump

 

having the same problem too

[skip pre-clear/clearing for new array and existing drives]

is there any way i could modify the existing drives partiton layout to match what unraid expects without losing the data on the drives or moving it about a bunch?

[skip pre-clear/clearing for new array and existing drives]

1 hour ago, Squid said:

You never need to actually pre-clear any drive.  If the drive isn't precleared, then Unraid will automatically clear it when adding it as a new drive to a parity protected array

 

Without a parity drive (or on a new config and assigning a parity drive), Unraid will not automatically clear any new additional drive

 

if i understand you correctly i woud have to do a big data shuffle when adding new disks? adding existing disks in a vm (pre-formatted as xfs) will give me the unmountable: unsupported partition layout error. my existing disks are all xfs and about 75% full of data. i think i might get the same error when trying with them.

i read somewhere that unraid partitions disks from sector 64 onwards and that might be the reason for the error since all my drives start at 0

 

and another thing just to clarify for me: if i somehow manage to add my disks to a new and unprotected array i could later add a parity drive without losing any existing data? (ofc if nothing fails beforehand)

[skip pre-clear/clearing for new array and existing drives]

hi,

if i setup unraid without a parity drive (for the moment) - do i still need to clear the drives i am adding to the new array? i am thinking about switching back to unraid but don't want to do the data shuffle with all my existing drives (all in xfs).

 

so tldr: new setup, no parity for now, add drives with existing data, skip clearing?, add parity drive later and establish parity.

[share suddenly marked as unprotected]

thank you for all your replies. its not the only share but its the main one i'm braking down into smaller ones later on. i found that there was a residual empty folder on the cache that did not get moved over. its all fine now - thank you again

[share suddenly marked as unprotected]

hi,

i have a share for all my data. i run 4 WD RED 4TB + 1 8TB as parity disk - with my old ocz ssd as cache. I reformated the cache drive as xfs after i noticed the huge read/write amount happening for no reason under btrfs. since then my share is marked as unprotected despite it not being cached at all.

 

 

i ran a full parity check and nothing changed (came back clean) - any pointers are appreciated?
