mounting external hard drive

[pinniger]

Ok, installed amahi via express cd (which was great), then I added two usb hard drives. I followed the wiki for adding a second hard drive except I used fdisk and mkfs.ex3 to format the disks. then i ran hda-diskmount and got this..

Code: Select all

**************************************************************** Ignoring /dev/sda1 - already in /etc/fstab or mounted **************************************************************** Mounted /dev/sdb1 as '/var/hda/files/drives/sdb1' (read-write) You may want your system to mount it every time you boot. To do so, add this line VERY CAREFULLY to /etc/fstab and reboot: UUID=F8FC641EFC63D582 /var/hda/files/drives/sdb1 ext4 defaults 1 2 **************************************************************** Mounted /dev/sdc1 as '/var/hda/files/drives/sdc1' (read-write) You may want your system to mount it every time you boot. To do so, add this line VERY CAREFULLY to /etc/fstab and reboot: UUID=959b66d4-533c-411f-a5e6-ad33b4a54621 /var/hda/files/drives/sdc1 ext4 defaults 1 2 **************************************************************** All Linux, Windows and Mac partitions on non-removable disks have been mounted

Perfect!

I check the disks in the dash board and everything looked great. I wanted to add them to the storage pool, so I followed that guide in the wiki. when I added the uuid lines to the fstab file, and then run "mount -a" I get this message "mount: special device UUID=F8FC641EFC63D582 does not exist"

I'd also like to mention that these are identical drives, and when I ran mkfs.ext3 on sdc, it only took 10 minutes or so, sdb took 2 days to complete, maybe the drive is failing? but then why does it mount ok when I run hda-diskmount?

Anybody know what is going on with this?

Your sdb drive is very probably dying.
It can mount sometimes, but will disappear soon afterwards, and won't be re-mountable until you reboot, where the same will happen again.
You can check /var/log/messages to look for errors; there's probably a lot of them, very cryptic error messages about ATA or something like that.

you can run smartctl on all your drives to check for their health (SMART output).

Code: Select all

root@host# smartctl -a /dev/sdb

[pinniger]

after I manually mount it, it stays mounted, it just doesn't mount when added to fstab...

results of smartctl...
It says the disk passed, so I assume its ok...for now.

Code: Select all

aha...
can you show us the /etc/fstab line you've added?
and can you make sure it's the same as the one listed when you give the following command:

Code: Select all

root@host# ls /dev/disk/by-uuid

[AndrewKevin]

You have to log in as root and then do

mkdir /mnt/harddrive
mount -t vfat /dev/sda1 /mnt/harddrive
