comment RAID 5 with big SATA disks. Do or don't?
RAID != backup. You will have backups, right?

comment RAID 5 with big SATA disks. Do or don't?
On the contrary, I would expect bigger drives to be faster than smaller drives. All else being equal (rotational rate, number of heads, physical size), a larger drive will have a greater bit density than a smaller drive, which implies that its read/write rate will be higher.

comment Recursively archive small files in document tree on linux?
Warning! If you want to use xargs or find -exec {} with tar, you really should be using tar -A, and NOT tar -c. See my answer for an explanation why.

comment Recursively archive small files in document tree on linux?
Danger! This will fail if/when the list of files grows longer than the maximum number of command-line arguments. xargs executes the given command more than once if it can't fit all the arguments into one command invokation. In this case, each time xargs runs another copy of tar -c, the tarfile will be overwritten, and the final result will contain only the last batch of filenames that xargs received. You really need to do a tar -A instead.

comment Boot problem empty fstab RedHat 3.7
This should work. However, I would wonder how/why /etc/fstab has been truncated. It is possible that the root filesystem is seriously borked, so it might not be a good idea to mount it rw until after a fsck.

comment Fair bandwidth repartition between multiple users
Thanks for the clarifying example. There are a number of related questions in ServerFault that deal with allocation of bandwidth among multiple concurrent users. Check them out: "QoS - split bandwidth across all IPs during high load"; "how can I limit per user bandwidth?"; "How bandwidth is allocated to concurrent users?"

comment Setting up Apache on Ubuntu to server subdomains on LAN
@TomC: I think that should probably be a separate question! The short answer is: consult your DNS server's documentation.
