agan2 sekalian gw nubi, mo tanya ttg raid1 pk software (bkn lwt bios/hardwer). mungkin agan2 ada yg pernah ngalamin.
gw lg nyeting server linux pk debian. gw ga pernah bs install raid yg pk hardwer krn mslh driver raidnya ga disupport. jadi gw buat pk raid sofwer.
gw mengikutin dari tutorial berikut:
http://howtoforge.com/how-to-set-up-...n-debian-lenny (http://howtoforge.com/how-to-set-up-software-raid1-on-a-running-lvm-system-incl-grub-configuration-debian-lenny)
semua sudah berjalan lancar sampe setting di grub nya jg, sampe test simulasi failure. kondisi raid kalo di liat pk cat /proc/mdstat lancar :
Code:
cat /proc/mdstat
Personalities : [raid1]
md1 : active raid1 sdb2[1] sda2[0]
35591936 blocks [2/2] [UU]
md0 : active raid1 sdb1[1] sda1[0]
248896 blocks [2/2] [UU]
unused devices:
trus, yg membuat gw ragu thd system ini adalah hasil fdisk -l, ada yg menunjukan masalah di md0 & md1 ttg partition tableny. hasil fdisk -l sebagai berikut:
Code:

gw pikir ada bad sector, tp sudah cek badblocks mo problemo. maaf bila infonya kurang memadai.
gw kurang pengalaman ttg filesystem di linux. mohon pendapat agan2 layakkah sistem ini dan kira2 solusi mengatasi masalah ini...
