Pogo E02 - How to change usb hdd?

My old ext ntfs hdd (Disk1) attached to the pogo plug e02 got bad sectors. had to remove it since the system would stop functioning with it attached. I did a file system check in windows and removed the errors as much as possible. One file was corrupt due to a bad sector, so I won't be using this drive anymore. Seems to have come to its impending doom after ~5 years in service.

I had put a rule in fstab for the Disk1 to automount.
I want to replace this fstab line with (Disk2) uuid.
I'm facing a problem. If I try to start pogo plug with Disk2, it wont start. The light is orange even after 1/2 an hour. It boots up properly with the disk removed. How do I put UUID of the new Disk2?
Should I:
1 - comment out the line in fstab auto mounting the old disk and save it.
2 - shut down the pogoplug and attach the Disk2
3 - see if pogo starts. if it starts, mount Disk2 to empty folder.
4 - get blkid of Disk2
5 - add the uuid of Disk2 to the fstab and save.

Is this the correct method? Asking cause I've hardly touched the plug from the last time I asked for instructions here. must have been months back.

Vinay,

It is best to use a partition label. And it's best done in u-boot env for bootargs. Then you will never need fstab again for booting correct rootfs.

If you like to do that then get the listing of current envs and post here.

fw_printenv

If you don't like changing u-boot env, then try this in fstab (replace your root device). For example,

LABEL=rootfs    /               ext4    noatime,errors=remount-ro 0 1

And label the rootfs partitition with: rootfs

Hi Bodhi,
I should have mentioned this earlier. My rootfs is on a Sandisk Usb disk. The disk I want to change (Disk2) is another external usb portable hdd. This Disk2 is what i want to put in fstab. I think I have put the rootfs in fstab too.

Do I need to change the /etc/fstab file too?
can i load another hdd through fstab with label (example: LABEL=backup) instead of uuid?

Vinay,

The envs looks good. It seems you have either Jeff or davygravy u-boot (circa 2012).

You don't need to change fstab, as far as rootfs is concerned. The kernel bootargs takes precedent, so that's enough to boot the correct roots. For the other drive, you could mount it in /etc/rc.local. Fstab is a fixed setting, so it does not have the flexibilty of mounting drives in rc.local. I usuall don't have anything in fstab, except for tmpfs when I need it. The root device specification in fstab is just a fallback when you use bootargs.

So if you use partition label, you can mount the other drive in rc.local like this (add more options after -o as you need):

mount -L backup -o noatime /media/backup

Thanks Bodhi. Worked like a charm. :)

I'm getting the same problem now. The plug will not boot up with the external hdd attached to it.

I've put both of these lines in fstab one at a time and tried to get the disk auto mounted. Both lines don't work. I have given full rw permissions to the /media/external folder for ntfs-3g to mount the disk. If I boot system without disk and connect disk afterwards and do a mount-a, the disk gets mounted.

#Label=SeagateExp   /media/external  ntfs-3g defaults,locale=en_US.utf8  0 0 
/dev/sdb1   /media/external  ntfs-3g defaults,locale=en_US.utf8  0 0

The same lines worked in older version of debian. Why its not working now?

Also, another question. Seems like Deluge uses only systemd to start properly now. It won't start up in systemctl or the init.d etc files like before. I'm sure I haven't put the device to use systemd in fw_setenv. Is it too late now? Do I have to start again from scratch to use systemd? I feel very old now after all this searching on google and nothing working.

Forget fstab, mount the 2nd disk in /etc/rc.local with label. If this disk parttion is labeled external, then

mount -L external -o noatime /media/external

You should use disk partition label to mount everything. Mounting with disk device letter will be problematic whenever you upgrade any part of the system that could alter the booting time.

I see a script for led lights which ends with exit 0. Should i put this mount command after exit 0 or before it?
Don't I have to put settings for ntfs drive, uid, gid, rw etc?

>Mounting with disk device letter will be problematic whenever you upgrade any part of the system that could alter the booting time.

Also what you mentioned about device letter is true. I was looking at dmesg with and without the external hdd. Seems the external hdd is mounted before the rootfs when the external hdd is present. Sometimes its loaded after rootfs. I don't know why its happening but it does.
I removed all entries related to the external hdd from fstab for now. I saw some error in dmesg. Is it bad?

How are hdd's loaded in uboot? top most port to bottom next to rj45 port or in reverse?

I think i figured out the problem. The external usb 3 hdd I'm trying to mount is a 1.5TB single platter hdd. Maybe the old uboot can't mount this capacity disk at boot.
It auto mounts a 1TB usb 3 disk without fail even after 2-3 boots. The boot time takes very long though. Like ~3-4 minutes. With or without the external hdd attached. Is there a way to shorten the boot times?

That's not true. Your current uboot can handle 1.5TB HDD just fine.

You need to observe the boot in serial console or neconsole to determine why.
