Reiser Selamat Lagi

Ditulis pada tanggal 12 Agustus 2008

Beberapa orang pernah bilang kalo reiserfs itu ndak aman. Banyak juga yang pernah ngomong bahwa filesystem itu kalo sama linux kernel versi sekian sekian ndak bagus. Ada juga kabar-kabar ndak bagus yang lain. Entah kenapa, tampaknya beberapa distro beberapa bulan yang lalu juga ada yang pernah mencabut penggunaan jenis filesystem itu, dan kembali menggunakan ext3, yang terbukti stabil dan memuaskan lebih banyak orang.

Terlepas dari itu semua, aku masih seneng aja sih pakai reiserfs. Kemarin adalah untuk ke-3 kalinya dataku selamat. Kebetulan aku pernah juga ngalamin filesystem rusak waktu pakai ext3, dan datanya ndak selamet. Ini potongannya:

[root@ck-mbl 11:16 ~]# mount /dev/sdc1 mnt/
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Lho, kok muncul gitu ya?? Terus aku coba lihat data partisinya pakai cfdisk. Hasilnya masih beres-beres aja. Ndak ada tanda-tanda yang aneh. Kemudian aku sempet pindahin ke komputer lain, masih aja gitu. Walah... Udah sempet kepikir selamet ndak selamet. Tapi kemudian, aku coba rebuild tree seperti ini:

[root@ck-mbl 11:18 ~]# reiserfsck --rebuild-tree /dev/sdc1
reiserfsck 3.6.19 (2003 www.namesys.com)

*************************************************************
** Do not run the program with --rebuild-tree unless **

** If you have bad sectors on a drive it is usually a bad **

** a working hard drive, copy the file system from the bad **
** drive to the good one -- dd_rescue is a good tool for **
** that -- and only then run this program. **
** If you are using the latest reiserfsprogs and it fails **
** please email bug reports to reiserfs-list@namesys.com, **
** providing as much information as possible -- your **
** hardware, kernel, patches, settings, all reiserfsck **
** messages (including version), the reiserfsck logfile, **

*************************************************************

Will rebuild the filesystem (/dev/sdc1) tree
Will put log info to 'stdout'

Do you want to run this program?[N/Yes] (note need to type Yes if you do):Yes

reiserfs_open: the reiserfs superblock cannot be found on /dev/sdc1.
Failed to open the filesystem.

If the partition table has not been changed, and the partition is
valid and it really contains a reiserfs partition, then the
superblock is corrupted and you need to run this utility with
--rebuild-sb.

Disuru pasang --rebuild-sb, ya udah aku jalankan lagi.

what the version of ReiserFS do you use[1-4]
(1) 3.6.x
(2) >=3.5.9 (introduced in the middle of 1999) (if you use linux 2.2, choose this one)
(3) < 3.5.9 converted to new format (don't choose if unsure)
(4) < 3.5.9 (this is very old format, don't choose if unsure)

The fs may still be unconsistent. Run reiserfsck --check.

Masih disuru njalanin lagi? Yo wis, dituruti lagi.

Lhah?? Baru inget kalo tadi rebuild tree belum berjalan sukses. Ya kujalankan lagi, seperti ini nih:
