comment install the same debian packages on another system
Just a minor note. According to the aptitude reference manual, the "package" field is "expandable" by default, so aptitude search -F '%p' '~i!~M' > package_list should also work fine.

comment grub2 does not find /boot on RAID1 md0 device
After a while (and a few forgotten manual grub installs, as described above, and also an extra HDD which changed drive letters), I've settled on booting from just a single drive's /boot partition - no RAID. Works beautifully.

comment Which Linux filesystem is best for a huge Apache mod_disk_cache partition?
Thanks for the update, I'm really curious what is the best FS option for your case. This post - permalink.gmane.org/gmane.comp.db.cassandra.user/8478 - suggests that ext4 might be superior to ext3 with high inode counts. Seems at least partially relevant.

No, sorry - I lack experience beyond that. Yes, ext3 with no journal is ext2, but I don't know how journalling impacts performance in your case. You mentioned slow performance during purge - maybe you could use ionice -c 3 on the purge cron job? That could really help, at the cost of slower purge. As you most likely understand yourself, testing a few options under your specific load would be best - provided you have time and resources to do that.

I suspect this doesn't help much, but Debian now has kFreeBSD kernel as an alternative to Linux kernel.

comment grub2 does not find /boot on RAID1 md0 device
I wonder if removing devices from md0 and installing grub2 onto them individually (one-by-one) will create/write correct grub images in bios_grub. Otherwise grub2 detects that it is being installed onto a raid component partition, and writes 'md0' into image.

comment grub2 does not find /boot on RAID1 md0 device
Thanks for the swap hint, will try that. As for GRUB2: I guess chainloading you describe is a little messier (need to manually prepare for that) than just have a hard-coded prefix for the "first HDD" - there will always be some "first HDD" on the system (assuming they all have GRUB2 installed to the bios_grub).

comment convert 1x2TB HDD with LVM into 2x2TB HDD with RAID1+LVM or with LVM mirroring?
I've documented the steps I've taken to achieve this conversion in more details.
