hi fvdw,

thing I changed was using a switch in between - before I had the NAS directly to the laptop.

indeed, I didn't get a new command prompt

I opened a new telnet session, but the mountpoint directory is empty :dontknow

thids is what I got:

maybe it is still assembling the array.
if you use the command "top" (without the quotes) you can see if mdadm is still running

otherwise you could give the command mdadm with option examine your raid array

Do you know which file system was used for the array, the standalone kernel (#24) supports ext3 and xfs
But in case the file system is not supported the mount command should give an error

You could try to leave away -o ro in your mount command

hi fvdw,

did the mdadm --examine /dev/sd[abcde]2 and sent you the output

so I think the assemble worked, however when I try to mount, it hangs

with regards to array file system ... how can I find out what the what the array was set up with?

[fvdw]

where did you sent the output ?

[cwherbert]

to you as a private message - not sure how confidential the output was ;) , sorry

[fvdw]

i did not receive it, you can post here, pm only work after you have made 10 posts

[cwherbert]

i think the NAS might be working in the background …? after i try to mount the assembled array

this is what I got from examine:
