Drobo s and linux

[Richard Shack]

I have a drobo s that has been installed to a windows home server. I would like to attach it to a new server that is using fedora. It is connected via USB 3.0. The server sees the drobo but I can't figure out how to mount it. Any suggestions?

Hi

It’s probably because Fedora doesn’t understand NTFS natively. You will have to install an ntfs driver, and use the ntfs file type.

It looks like I have an ntfs driver.  When I type:

Mount -t ntfs /dev/sdc1 /mnt

I get the following error:

NTFS signature is missing.

Failed to mount '/dev/sdc': Invalid argument

The device '/dev/sdc' doesn't seem to have a valid NTFS.

Maybe the wrong device is used? Or the whole disk instead of a

partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

Try sdc2 . Windows puts special partitions on disks so your data drive might not be the first one...

Tried sdc2 just to see.  No change. Here is the output of fdisk -l for the drobo:

Well that’s not right.

I have an old drobopro sitting on a Linux system - not fedora though - and here’s what it looks like

Note the partition type and the fact the data is on the 2nd partition.

Yours says it’s a Linux partition on the first partition.  Are you sure this is from a windows box? To me it Looks like it’s ext2, not ntfs. Try mount -t ext2 /dev/sdc1 /mnt 

——- cut here ——

 fdisk -l /dev/sdq

Here is what happened when I tried ext2:

[admin@localhost drives]$ sudo mount -t ext2  /dev/sdc1 /mnt

mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sdc1, missing codepage or helper program, or other error.

[Richard Shack]

It was on windows home server so I assume it was ntfs.  

I have installed drobo-utils but it can't find my drobo:

[admin@localhost drives]$ sudo drobom list

expected 8, got 15 bytes

No Drobos discovered

Hmmmm

I think there is something wrong with the partition.  Did you create the partition and format it in fedora ? Or was the partition created under windows? My guess is it’s been created in Linux , but not formatted.

 Format it with mk2fs 

(mkfs -t ext3 /dev/sdc1 ) then mount it (mount -t ext3 /dev/sdc1 /mnt ) and go from there. 

It’s been a while since I’ve touched my drobo and so I haven’t kept up with it - not sure if ext2/ext3 is supported at 16tb. It isn’t in my drobopro, which is why I use ntfs on the drobopro in my Synology.

@rks...@gmail.com, the limit on a drobo s is 16TB IN TOTAL ..

@eus...@gmail.com - not meaning to hijack , I'd think seriously about using as non critical storage or getting rid of the Drobopro, I have one which suddenly started to lose and corrupt data randomly, Drobo wouldn't even check the logs for me because it's out of support.  the it took about a week to remove the data from the drive.

@temp...@gmail.com - You arent hijacking :) I was just trying to help because I have this (almost exact) situation - a windows format drobo on a unix/linux box :)

Dont worry its non-critical storage. I quickly found out its awful drobos were after I had my own issues with them.. I have 2 - they are unreliable, flakey, slow, and dont do what they are supposed to so (iscsi is a joke) - I replaced them a long time ago with a 12 bay synology box with raid6. They were both sitting in a cupboard until recently, when I decided to see if I could get them working with the many 1 and 2 TB drives I have floating about doing nothing...

So - the drobopros are attached to the Synology as a "last resort backup", in case everything else fails. One works ok for this, the other not so much....

Unfortunately I found my problem.   The file system seems to be corrupted.   I put the drobo back on a windows machine and the volume still won't mount.  

Looking at recovery but options aren't great.

@Laura - yes, note the comments from euston and myself, I was horrified when I found the file corruption and I still don't know how many files were corrupted.  Worst of all was Drobo's failure to offer any help at all, they shouldn't give the B.S. about how wonderful their devices are; people like me take them at their word, I stored Terabytes of data - expecting "beyondRAID" to work properly.  I've never lost data before and I won't make the same mistake again.
