xfs data loss

[Passerone, Daniele]

I would like to ask mr. Peter Grandi, whether it is really necessary to delivery ist vaste knowledge in such a harsh way.
Is this the habit of this mailing list?

Apart from that, thank you for you help. 
I understand that RAID5 is not the ideal solution for that system, and I admit that
in the urgence of solving the /md4 problem I miswrote the problem of /md6, which 
of course was "erased" and not "repaired".

But apart from that, it is not as easy to backup 20 TB, so we decided to set it as
data storage leaving the responsibilty of the backup to our users.
I do not consider it completely absurd.

Moreover, when a raid loses 2 devices, and the devices are still ok, it is possible
to reassemble the raid by assuming the devices clean.

This is not the case for /Raid/md4, where apparently all devices are there.

THanks,
Daniele
