ReadyNAS 104 w/ 6.4 firmware in X-RAID mode is not expanding after adding disks

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.

Hi knelson454,

 

Welcome to the community!

 

Can you confirm if all(4) 2TB hard drives were recognized in the volume tab as well as in the ReadyNAS logs? Also attach (steps are found here) the current device logs so we can have a further look. 

 

 

Kind regards,

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. KN

Re: ho to rename /var/backups/data-1_backupfile to /var/backups/data-1_backupfile_old

mv /var/backups/data-1_backupfile /var/backups/data-1_backupfile_old

 

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.

Re: ReadyNAS 104 w/ 6.4 firmware in X-RAID mode is not expanding after adding disks

Hi Guys,

I went back into the directory and see the folder "/var/backups/data-1_backupfile_old", but when I restarted it I assumed it would make a New folder "/var/backups/data-1_backupfile" which I do not see.

Does the NAS need to shut all the way down, power off or just a restart OK? I've only just restarted it.
