Drobo-FS config files exhibiting input/ouput error
I have a Drobo-FS with DropBear installed via DroboApps which allows me SSH access into the linux operating system which powers the Drobo-FS.
The Drobo-FS file system has a directory which looks like this
# ls /mnt/DroboFS/System
DNAS avahi netatalk samba
Each of the directories listed has a conf or similar directory within it and for me the samba, netatalk and avahi conf files all exhibit an Input/ouput error
# ls /mnt/DroboFS/System/samba/conf
ls: /mnt/DroboFS/System/samba/conf/scratch.smb.conf: Input/output error
ls: /mnt/DroboFS/System/samba/conf/smb.conf: Input/output error
# ls /mnt/DroboFS/System/netatalk/conf
ls: /mnt/DroboFS/System/netatalk/conf/afpd.conf: Input/output error
ls: /mnt/DroboFS/System/netatalk/conf/AppleVolumes.default: Input/output error
# ls /mnt/DroboFS/System/avahi/conf
ls: /mnt/DroboFS/System/avahi/conf/scratch.avahi-daemon.conf: Input/output error
avahi-daemon.conf
I have read that this behaviour is indicitive of a hard-drive failure or a loose cable (I assume connecting the drive to the controller.) However this is not an ordinary Linux box, so my first question is
What device is /mnt/DroboFS/System stored on. I assume it cannot be on a hard-drive in any bay, and must therefore be on some other internal drive or flash memory. If so does this mean my Drobo-FS is faulty?
Also the question has to be asked: why have only the configuration files been affected?
Or could this problem run deeper?
Additionally could anyone with specifically a Drobo-FS and frimware version 1.2.0 provide their versions of the following files?
/mnt/DroboFS/System/samba/conf/smb.conf
/mnt/DroboFS/System/netatalk/conf/afpd.conf
/mnt/DroboFS/System/netatalk/conf/AppleVolumes.default
With that I could replace the seemingly corrupt files with the correct versions.
And finally, if the Drobo itself is faulty, is the RAID (or BeyondRAID) configuration data stored within the hard drives themselves or the drobo. In other words can I move the existing drives to a new drobo without data loss?
Edit: I can answer my own question here. I discovered this is possible if you move all Drobo disks as a "disk pack" to a new Drobo. The order/position of each drive must to be maintained for this to work.
Edit: Result of cat /proc/mounts
# cat /proc/mounts
rootfs / rootfs rw 0 0
/dev/root / jffs2 rw 0 0
proc /proc proc rw 0 0

ls -ld /mnt/DroboFS/System should tell you and allow you to identify which device it is; if it ain't a symlink to something else it is more likely be the case that your hard drive is faulty so you might need to replace it, assuming the cable is properly connected and intact.
