[SOLVED] Added disk, array will not mount

[cowgill]

I am finishing up a mass upgrade of my server where I've upgraded to the latest RC of 5.0, replaced the 2TB parity drive with a 3TB, added a cache disk, and now I'm trying to add a 3TB data disk to the array. Everything has gone smoothly up to now.

 

I ran preclear on the 3TB data drive and added it to the array while stopped via the webgui, then told it to start the array. Nothing seems to happen and I cannot refresh the webgui. The flash drive is still mounted on the network and I can telnet into the box just fine, but the webgui and array are both down.

 

Syslog is too large to be attached (ask if you need more and I'll find a way), but these lines seem to be relevant:

May 19 15:39:28 Tower emhttp: shcmd (53): mkdir /mnt/disk5
May 19 15:39:28 Tower emhttp: shcmd (54): set -o pipefail ; mount -t reiserfs -o user_xattr,acl,noatime,nodiratime /dev/md5 /mnt/disk5 |& logger

May 19 15:39:28 Tower emhttp: _shcmd: shcmd (54): exit status: 32
May 19 15:39:28 Tower emhttp: disk5 mount error: 32

 

 

Any ideas? I've tried searching for mount error 32 and bad superblock but am coming up with nothing.

Are you running "stock" UnRAID -- i.e. no plugins or add-ons?

 

If not, try that.

 

Also, what license level do you have?

Actually, if you just pre-cleared the drive and just assigned it, those lines are entirely expected and normal. 

You cannot "mount" a file-system that has not yet been created, and you've not yet formatted the disk to create the file-system.. 

 

Right now, I am guessing that the array can be started, but that the new drive will display as unformatted.  There should also be a "Format" button present (with a checkbox under it to enable it)  Check the box, press the "Format" button (assuming the new drive is the ONLY drive showing as unformatted) and a few minutes later, the new drive should be formatted, mounted,  and be available for use for data.

unRAID Server Pro  version: 5.0-rc12a

I am running the Subsonic 4.8 plugin on the cache drive. I may have remnants of old addons I don't use anymore. What is the best way to check what is still running? How do I get rid of all plugins/addons?

Hmm, I am not seeing a format button anywhere and I cannot start the array, when I try to start the array is when it will "lock up". I tried restarting the server and trying it again, and that's where I am now. Here are some screenshots of where my webgui is now:

Update:

Gary I think you were spot on asking about plugins. I went into my config directory on the flash and renamed some old plugin files that i wasn't using anymore from ".plg" to ".plg2". Now the array started right up and went into a parity check. I also now see the format button for the new disk which I will do after the parity check is complete.

 

I haven't quite completed the addition of the drive to my array yet, but I'm going to knock on wood and mark this topic solved.

 

Thanks Gary and Joe for the help.
