Hei alle sammen.
Jeg har et problem med et linux raid jeg har på en RedHat 7.3 installasjon.
Slik ser det ut når jeg kjører komandoene lsraid -A -a /dev/md* og fdisk -l:
# lsraid -A -a /dev/md0
[dev 9, 0] /dev/md0 53389405.21EF1962.D1052F68.9B857927 online
[dev ?, ?] (unknown) 00000000.00000000.00000000.00000000 missing
[dev 8, 19] /dev/sdb3 53389405.21EF1962.D1052F68.9B857927 good
[dev 8, 35] /dev/sdc3 53389405.21EF1962.D1052F68.9B857927 good
#lsraid -A -a /dev/md1
[dev 9, 1] /dev/md1 24BCB050.23C4C3B6.3D31F625.FFE1B825 online

# lsraid -A -a /dev/md2
[dev 9, 2] /dev/md2 21082245.440913EE.9EB56DE1.EA5396DE online

# fdisk -l

Er det noen som vet hva som har skjedd galt her:
# lsraid -A -a /dev/md0
[dev 9, 0] /dev/md0 53389405.21EF1962.D1052F68.9B857927 online
[dev ?, ?] (unknown) 00000000.00000000.00000000.00000000 missing
[dev 8, 19] /dev/sdb3 53389405.21EF1962.D1052F68.9B857927 good
[dev 8, 35] /dev/sdc3 53389405.21EF1962.D1052F68.9B857927 good
Kan det være at jeg har satt noen av jumperene feil på en disk?
/dev/md0 er et raid 5.
Jeg er ikke så flink med raid, så jeg håper noen kan hjelpe meg.
Mvh.
