Thread: RAID problem killing me

-

i bought 2x hp 40l microservers assist nas house , @ office. after reading selected ubuntu server (older version) way forward. fitted each out same ram (2x 4gb eec each) same hdds (4x seagate 2tb drives). servers boot 8 gb kingston flashdrive.

installed cd rom, after installation idea remove cdrom pc's not require one. followed how-to found on: http://www.studiob.co.za/setupnas.html

first server worked charm, , doing service backup nas @ office. use 3 of drives in raid5 4th drive hot spare. has been working silently , brilliantly week.

have been unable setup raid on other machine. @ first did not show linux raid under hardware, after trying few hints other websites, reinstalled. same problem. needless say, followed procedure used first pc exactly. again no linux raid under hardware (in webmin).

third install left harddrives connected pc , manually pointed flashdrive. after install , after setting webmin, granted linux raid under hardware.

however, no matter cannot mount it. have read every page in regard find, tried it. nothing. created directory /nas, when try mount following error:
code:
mount: wrong fs type, bad option, bad superblock on /dev/md0,         missing codepage or helper program, or other error         in cases useful info found in syslog - try         dmesg | tail  or so
whatever may mean.
code:
> dmesg | tail  [40224.585852]  disk 2, o:1, dev:sdc1  [40224.585856]  disk 3, o:1, dev:sdd1  [40224.585912] md0: detected capacity change 0 6001193189376  [40224.588835]  md0:  [40224.588845] md: resync of raid array md0  [40224.588854] md: minimum _guaranteed_  speed: 1000 kb/sec/disk.

[40224.598473]  unknown partition table  [40256.836868] ext2-fs (md0): error: can't find ext2 filesystem on dev md0.
i followed instructions exactly, , sure selecting ext3 file system.
hhhmmm ... perhaps have solved myself. lemme try mkfs ext3 /dev/md0 ...
