15.1 and External USB disk docking station

[mdi]

Hi Jocko,
I will try that formatting you suggest, but I don't really understand why they are necessary. -j means to create an ext3 journal. Shouldn't it be supposed to be an ext4 journal instead? The -m 1, I don't understand it, but I can try.

Just after unplugging everything (only the docking station) and restarting after more than 1m, the dmesg is the following:

Sounds ok to me.

[Jocko]

Your dmesg seems ok

So wait...

[mdi]

Formatted with your command in the meantime :snicker
dmesg seems slightly different:

I will let you know if it resist :)
Should I assume that with -j the journal is created and managed by the NAS, otherwise not, creating problems when accessing the disk?

[Jocko]

I don't see where is the change in your last dmesg :scratch

[mdi]

It seems to me that on the newest dmesg there's no "recovery complete" message on the external disks, while there was before.

I also read around that -j is actually redundant and I understood what -m is used for. Thanks for teaching me something interesting! :)

Tonight I have a backup scheduled to be run. Let's see the results tomorrow. I will let you know. Sorry for my continue need for help, but you're helpful :)

[Jocko]

Indeed option j is useless for ext4 (by default it already has one)

[mdi]

:dontknow
Now I'm a bit stuck. This morning the disks were again both unmounted and dmesg shows a lot of I/O errors, their fs remounted as ro and then again errors.

They would be just "tests" but I can try the followings:
- just attach 1 disk to the docking station;
- using a USB extension to try if it helps the NAS with the power absorption of the USB3 of the docking station;
- directly connecting 1 disk with a sata-USB cable (so it will be USB2);

At least the above could help to know if it's the docking station causing the issue.... :sob

[Jocko]

Hi mdi,


maybe tune2fs command could return some informations :scratch

Code: Select all

tune2fs -l /dev/sdc1

You can try to add the option 'debug' in the mount command to get more information in dmseg (or in messages file):

So umount the usb disk (twice : in /mnt and /share/1000) and use this command to mount them again

Code: Select all


mount -t ext4 -o -o noatime,debug /dev/sdb1 /rw_fs/tmp/mnt/data1_1
mount --bind /rw_fs/tmp/mnt/data1_1 /share/1000/data1_1

(to repeat with sdc)

[mdi]

I mounted like suggested. Here the output for tune2fs -l /dev/sdb1:

[Jocko]

Thank mdi,

I don't understand nothing i have the same outputs than you for my ext4 disk :scratch and I don't have the unmount issue...

Indeed it's amazing that tune2fs doesn't find the last mount point of your sdc1.

So wait if the disks are unmounted again and see what trace there is in dmesg or in the syslog journal with the debug mode...


Note : You must also start syslogd
