Cannot access 5big network 2

Theoretically you can use fdisk to create a partition on it, and the use mke2fs to create a filesystem.

But there is something strange. You built the raidarray from /dev/sd[abcd]2, and according to /proc/partitions sde has no partitions. That is consistent.

But your 'fdisk -l' shows that /dev/sde *has* partitions, and doesn't show sdd. What does 'fdisk -l /dev/sdd' give?

So it is ok now, you can see sde.

You need to create the partitions table as you erase it and format it.

Please wait a moment.

It looks like:
sda = slot1
sdb = slot2
sdc = slot3
sde = slot4

That is weird isn't?

Well, it seems that not the disk is the problem, but the Lacie. You plugged a new disk, it was visible at some moment, and later it disappeared. Just like the old 'defect' disk.

Don't know how to go further, for the moment. What do you still need from that array? Only the big files? How many?

The weird thing those problems began after I resized the iSCSI to 1TB.

It would be grateful if I can still pull a lot of files from the Lacie. The really big files is less than 20 I guess.

If it is the Lacie I should not have seen this behaviour in the other Lacie when I swapped all disks. The other Lacie had the same symptoms unfortunately.

For the small ones you can use the ftp server, I guess?

That is true. Hm. Did I miss something? Jocko?

pacco,

To understand please to report at each post if you run udevstart and post the output
Code: Select all
ls -l /dev/sd[abcde]
cat /proc/partitions|grep -r /dev/sd[abcde]$


I can not follow you if you don't update at each the dev node as sometimes sdd is sde and sde is sdd...

Should I reboot and follow every step closely and report? Are we sure udevstart is ok? Mijzelf earlier told me to run mdadm --assemble /dev/md0 /dev/sd[abce]2 --run without running udevstart. That worked. Later you or Mijzelf asked me to first run udevstart and then mdam with abcd.

To me (as a very big novice) is appears d and e are swapped! Can we look up the physical location?

For now:
Code: Select all
root@fvdw-sta-kirkwood:/ # udevstart
root@fvdw-sta-kirkwood:/ # ls -l /dev/sd[abcde]
brw-rw----    1 root     root        8,   0 May  3 11:01 /dev/sda
brw-rw-r--    1 root     root        8,  16 May  3 11:01 /dev/sdb
brw-rw----    1 root     root        8,  32 May  3 11:01 /dev/sdc
brw-rw----    1 root     root        8,  64 May  3 11:01 /dev/sde
root@fvdw-sta-kirkwood:/ # udevstart
root@fvdw-sta-kirkwood:/ # cat /proc/partitions|grep -r /dev/sd[abcde]$
root@fvdw-sta-kirkwood:/ #
