System failed to expand [Volume 2] with disk [3]


Recommended Posts

My spec

N54L boot loader 1.01 DSM6.0.2

3 x 3TB and 99% full

 

When I try to add 1 more 3TB disk and add disk, I got error system failed to expand.

 

I then googled and tried to telnet and fsck.ext4 but still no luck.

 

I then tried to pull out 1 disk and system degraded, added the new disk for repair but I got error "System failed to repair [Volume 2] with disk [3]."

 

I think backup and rebuild the whole volume is the only option?

whats the new disk? is it new or used? did you run a s.m.a.r.t. check? maybe a check with the check tool of the manufacturer?

there should be more details about why it does not work

especially when you broke your raid on purpose and tried to rebuild to the new disk, there would be no operation to the file system, it would be just a sector by sector copy job on the lower level (mdadm raid) - be careful with this new disk and look into it before trying to make it part of you raid
