Raid problem (B3 and S1)

Post by snipes19 »

Hi,

i try to install a raid-system with my B3 (2TB) together with an eSata S1 (2TB).
I installed my B3 from scratch and updated the firmware to the version 2.5.1.2.
After connecting the S1 via eSata i tried to build the raid.

After approx 60% of the setup this message appears:

Code: Select all

Caught error: Error: Operation failed in command /usr/sbin/diskmanager disk format /dev/md0 ext3 at /usr/lib/web-admin/diskdaemon.pl line 832. 
Both disks, the internal and the external are deleted so i have to install my b3 again.

What's going wrong? What can i do?

Regards,
Michael

Its really strange that the master disk got corrupted, especially because the mirroring is done on a partition base, not on a disk base. Can you confirm the whole disk is buggered?

The operating system is still running, i can access the system. The web-interface shows error-messages. Some directories on the internal disk have been deleted and the raid-setup is stopped during installing...

So the disk is ok, but the partition is deleted. Are you able to log into the ssh shell? If so, can you show the output of these commands?

Code: Select all

mount
Cat /proc/mdstat
mount -a

Odd, does that mean there is no mount line in /etc/fstab for /home? How did you log onto the b3 without /home being available? Are you booting from a rescue usb?
Can you post the content of /etc/fstab? And maybe also those of 'lvdisplay'' as well? Sorry this takes so long, debugging through a forum is tedious with many questions giving unhelpful results from the system...

hi nobody,

good news, now the raid is working.
i found following information:
http://wiki.excito.org/wiki/index.php/U ... _3TB_disks

After installing this bootloader-fix, i installed my b3 once more from scratch (firmware 2.4.1.1)
Now the raid was build successfully. After installing the raid, i upgraded to 2.5.1.2 - it seems to work :D

:?: Maybe there is a problem to install the raid with the firmware 2.5.1.2?? :?:

After installing the bootloader-hotfix i tried the following way 3 times:

- install from scratch with 2.4.1.1
- upgrade to 2.5.1.2
- setup raid-system via web-interface
- installation failed

this works:
- install from scratch with 2.4.1.1
- setup raid-system via web-interface
- upgrade to 2.5.1.2
- successfull raid installation

Many thanks for your help !!!!!
Regards, Michael
