Partitions fail to activate on RAID volumes with complex names

It looks like dmraid needs fixed to backslash escape the spaces in the name before passing it down.

Adding the kernel to the bug since it appears that even when the spaces are backslash escaped, the kernel does not handle it properly. It appears that dm_split_args() properly parses the argv when the spaces are backslash escaped, but linear_ctr() still fails with "Device lookup failed".

Nevrmind, I must have made a typeo because now the kernel accepts names with spaces if they are backslash escaped.

I tried backslash-escaped spaces, as instructed to in the ubuntuforums thread.
Unless...by backslash-escaped spaces do you mean "\ " instead of "\"?

Yes, backslash escaped means prefixing the space with a backslash, so "\ ". You should be able to manually create the partition device with dmsetup but dmraid needs fixed to insert the backslashes before sending the path down to the kernel.

Can you test 10.04 or 10.10 and see if this is still an issue?

I've updated my desktop storage twice since I posted that and no longer have
a RAID setup, sorry.

determined that the partitions fail to activate, probably because the volume
name includes spaces. dmraid -Rd output is attached.

[Expired for dmraid (Ubuntu) because there has been no activity for 60 days.]

I spend about 6 hours trying to get my RAID working, finally I came across this bug and it looks very similar to what I was experiencing. I used Intel Storage Manager in Windows to remove the spaces from my volume's names. After doing so, everything worked perfectly... this is definitely still an active bug. (ubuntu 11.10, ICH7)
