about 3 days ago i had a HDD go bad thats ok im waiting on the RMA which should becoming tomorrow

so disk 1 was being emulated

xfs Unmountable: Unsupported partition layout

thanks for your reply this is the log

 

Phase 1 - find and verify superblock...

Phase 2 - using internal log

- zero log...

- scan filesystem freespace and inode maps...

- found root inode chunk

Phase 3 - for each AG...

- scan (but don't clear) agi unlinked lists...

- process known inodes and perform inode discovery...

- agno = 0

- agno = 1

- agno = 2

- agno = 3

- agno = 4

- agno = 5

- agno = 6

- agno = 7

- agno = 8

- agno = 9

- agno = 10

- agno = 11

- agno = 12

- agno = 13

- process newly discovered inodes...

Phase 4 - check for duplicate blocks...

- setting up duplicate extent list...

- check for inodes claiming duplicate blocks...

- agno = 0

- agno = 1

- agno = 2

- agno = 4

- agno = 3

- agno = 5

- agno = 9

- agno = 6

- agno = 8

- agno = 7

- agno = 11

- agno = 10

- agno = 12

- agno = 13

No modify flag set, skipping phase 5

Phase 6 - check inode connectivity...

- traversing filesystem ...

- traversal finished ...

- moving disconnected inodes to lost+found ...

Phase 7 - verify link counts...

No modify flag set, skipping filesystem flush and exiting.

Quick question, is the model of the drive the same as the one you RMAed? Same day of purchase, same order?

the model of the drive which is a RMAed is to replace disk 1 which is a 6TB WD Red pro

 

ive done the Rerun without the -n

done

 

done a restart of the array and disk 7 is Unmountable: Unsupported partition layout

 

also as i have 2 parity drives ok parity 1 is disabled for some reason im sure that was from crc errors

parity2 i hope is standing in for disk 1 which im waiting for my RMA today at some point

what is the best thing to day about disk 7 ?

as it looks like ive only got 1 parity drive running

This error means the partition is the problem, not the filesystem, i.e., the partition doesn't conform to Unraid standard, which is quite strange if it was working before, rebuilding the disk would re-create the partition and keep the data (assuming parity is valid), but I wouldn't try that before fixing the other disabled disks.

But you really need to rebuild disk1 also. And it isn't showing in your latest diagnostics. Why?

disk one is being emulated i guess from the 2nd parity disk

 

the drive was dead its been taking out sent back for a RMA which i should be getting today should i replace this before i try

 

To re-enable the 1st parity disk (Using the same disk) do the following:

Stop the array

unassign the drive

start the array to commit the current assignments (and ‘forget’ the drive just unassigned)

Stop the array

assign the drive

start the array to rebuild the drive (either parity or data as appropriate).

This is what im worried about

when i get the replacement disk for disk 1 and go to start the array its going to say do a parity sync to copy data back over to the new disk

 

would it also force Disk 7 (discarding all data currently on those disks) to format as thats what i keep getting on the Array Operation panel

ive only got one parity drive working with a 2nd faild hdd being emulated with a 3rd hdd Unmountable: Unsupported partition layout

it dont say it's disabled or being emulated does that just mean the files are not being seen

ok its doing a parity sync on to the 1st parity dive only 26 hours togo

disk 7 was able to stay as it was

 

would you say after that i should replace my disk one with the new RMA'ed one and the do a parity sync to just that

 

or

format disk 7 and replace disk one and do both at the same time

Just now, gavin_UK said:

wouldn't it just be replaced from a parity sync ?

Format is a write operation. It writes an empty filesystem to the disk. Unraid treats that write operation just as it does any other write operation, it updates parity. So after formatting a disk in the parity array, parity agrees the disk has an empty filesystem.
