ReadyNAS 104 w/ 6.4 firmware in X-RAID mode is not expanding after adding disks
Hi, I've read through this community and can’t find my exact problem so here it goes. I’m adding 3 2TB drives to the RN104. I had 4 drives in my RN104, from 1 thru 4 was a 1TB, 500GB, 500GB, and a 2TB. In this configuration I had approx. 1.3TB usable space,
I removed the 1TB and replaced with a new 2TB, waited for resync and then restarted. New size after restart is 2.7TB usable. Then here is where I had the issues. I removed the first 500GB (#2 slot) and installed another new 2TB, the NAS then started Resync, but it came up resyncing at 75% completed right away, not from 0% like the previous drive. I let it finish, about 9 hours, restarted 3 or 4 times but it still has same size of 2.7TB usable space. So I thought maybe I need to change the last 500GB before it got bigger, so I did that, removed last 500GB (#3 slot) and added my 4th 2TB.. It also started resyncing at 75%, but I let it finish, about 9 more hours. So when all done I restarted 3 or 4 times now and it’s still says 2.7TB size. With now having 4 2TB drives I'd imaging it should go up to around 6TB. It still seems to work OK, all drives are recognized as 2TB but it’s not getting bigger. Did I do something out of order? Any help would be greatly appreciated... I would like to fix this without having to rebuild. KN.

Looks like your other two disks are marked as spares in the expanded array.
Check the mdstat.log and look at /dev/md/data-1.
As per rn-expand.log, your reshape failed.
This line specifically is outputting the issue:
Oct 18 02:40:56 Jupiter rn-expand[2923]: output: mdadm: added /dev/sdb4;mdadm: level of /dev/md126 changed to raid5;mdadm: Need to backup 128K of critical section..;mdadm: /dev/md126: cannot create backup file /var/backups/data-1_backupfile: File exists;mdadm: aborting level change;unfreeze;mdadm: level of /dev/md126 changed to raid5;mdadm: Need to backup 128K of critical section..;mdadm: /dev/md126: cannot create backup file /var/backups/data-1_backupfile: File exists;mdadm: aborting level change;unfreeze;
I suspect if you rename /var/backups/data-1_backupfile to /var/backups/data-1_backupfile_old, and restart your RN, it will try to convert your RAID 1 to RAID 5 as part of X-RAID.
- Hi,Kohdee. I read the logs and see the issue. My problem is I don't know how to rename the folder in question. I assume I need to Enable SSH and get to the root but what do I do from there? does ren rename the folder? I never used SSH. I learn fast though. Thanks for any additional help.

If you use putty, you can cut/paste it from this post.
Hi StephenB,
I was able to log in via Putty (also used Tera Term) using root and password and was able to copy and past the line you sent. I did it twice just to make sure. The first time after return it went back to command prompt, second time it said file not found so I assume the first time it renamed the file to OLD.
I have since restarted the ReadyNas 3 times and no love. The NAS is still saying 2.71TB and has not, that I can tell, said its trying to expand.
I appreciate you guys help. Anything else I can try? If not I guess I will reinstall OS this weekend. Thanks, KN.
- thanks for the help guys but I rebuilt the server last night.
