Hi
Been trying to move my home directory over to reiser4, and I ran into
some issues, this is what I did:
PASSCODE="temptest"
echo $PASSCODE | cryptsetup luksFormat /dev/sdf6 -c
twofish-cbc-essiv:sha256 -s 256
echo $PASSCODE | cryptsetup luksOpen /dev/sdf6 tempHome
mkfs.reiser4 -o create=ccreg40,compress=lzo1 /dev/mapper/tempHome
mount -t reiser4 -o noatime /dev/mapper/tempHome /mnt/x
rsync -vax --progress /home/neuron/ /mnt/x/
During rsync I noticed this in top while moving over a virtualbox image:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
2427 root 20 0 0 0 0 R 100 0.0 14:32.01 pdflush
9497 root 20 0 0 0 0 R 100 0.0 11:38.48 rsync
It did continue, but I figured something was wrong, so I interrupted the
rsync and unmounted. The rsync reported my copy speed was down to
3-4mb/sec. This is on a fairly new quad core, so I should be able to
encrypt and compress the data without difficulty.
I remounted and started again, it starts by coping at 14-15mb/sec, and
then just slows down as pdflush hits 100% cpu usage. Iowait also goes
down to around 5%. When I interrupt it pdflush disapears instantly, and
rsync sticks around for 10-15 seconds (making it unmountable for that
period) until it dies.
The file it's having problems with is a 6.8gb virtualbox image I use as
a gentoo test enviroment.
