Auzind de beneficiile aduse de reiserfs, am avut curiozitatea sa`l testez
si
eu si, pentru asta, am copiat (cu mc), cu cateva mici modificari, toate
fisierele din / , din vechea partitie cu ext2 (hda3) intr`o partitie noua
(hda2) cu reiserfs, iar apoi am folosit`o pe cea noua pentru a monta /.
Uitandu`ma la overhead`ul fiecatui sistem de fisiere am constatat
urmatoarele:
[root@lan-202 /]# cat /proc/mounts
/dev/ide/host0/bus0/target0/lun0/part2 / reiserfs rw 0 0
none /dev devfs rw 0 0
none /dev/pts devpts rw 0 0
none /proc proc rw 0 0
#reiserfs
[root@lan-202 /]# umount /proc
[root@lan-202 /]# du -ks
3490047 .
#ext2
[root@lan-202 /]# mount -t ext2 /dev/hda3 /mnt/hda3
[root@lan-202 /]# cd /mnt/hda3
[root@lan-202 hda3]# du -ks
3559060 .
[root@lan-202 hda3]# df
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/ide/host0/bus0/target0/lun0/part1
5615184 4136000 1479184 74% /
/dev/ide/host0/bus0/target0/lun0/part3
4031680 3559076 267804 93% /mnt/hda3
reiserfs: "Used" - "du -ks /" = 4136000K - 3490047K = 645953K
ext2: "Used" - "du -ks /" = 3559076K - 3559060K = 16K
Oare de ce overhead`ul la reiserfs este asa de mare (645953KB) ?
