Hi Phil,
hello List.

This would be also very interesting - just in case:

Hopefully it will never happen, but if the raid 10 array crashes, what
information will be the most usefull for later recovery? Is this the output of
cat /proc/mdstat or as mentioned by Phil the output of mdadm --detail or what
ever?

I would like to be prepared and write a small shell script which will write this
to a file to be included in the backups.

What information about the raid would you suggest to collect and to save
somewhere to have it handy in case it is needed?

Thank you very much for your help.
Stefan


P.S.: Phil, thank you so much for the hints regarding moving the data. It looks
very promising. I'll know more in detail tomorrow. pvmove is taking all night, I
guess.
