Извините что отнимаю у Вас время у меня возникла проблема
по райду 1 никак не могу найти человека разбирающегося может поможете
У меня рейд 1 массив - два винта
Решил добавить еще два. Сделал raidhotadd 3 и 4 винта
Написало все ОК
Подправил raidtab
=================================
raiddev /dev/md1
raid-level 1
nr-raid-disks 4
chunk-size 32
nr-spare-disks 0
persistent-superblock 1
device /dev/scsi/host1/bus0/target0/lun0/disc
raid-disk 0
device /dev/scsi/host1/bus0/target1/lun0/disc
raid-disk 1
device /dev/scsi/host1/bus0/target2/lun0/disc
raid-disk 2
device /dev/scsi/host1/bus0/target3/lun0/disc
raid-disk 3
========================
смотрю /proc/mdstat
========================
Personalities : [raid1]
read_ahead 1024 sectors
md1 : active raid1 scsi/host1/bus0/target3/lun0/disc[3]
scsi/host1/bus0/target2/lun0/disc[2]
scsi/host1/bus0/target1/lun0/disc[1]
scsi/host1/bus0/target0/lun0/disc[0]
35843584 blocks [2/2] [UU]
unused devices: <none>
========================
Все винты стали, но только два винта в зеркале.
Смотрю /var/log/messages
========================
raid1: spare disk scsi/host1/bus0/target3/lun0/disc
raid1: spare disk scsi/host1/bus0/target2/lun0/disc
raid1: device scsi/host1/bus0/target1/lun0/disc operational as mirror 1
raid1: device scsi/host1/bus0/target0/lun0/disc operational as mirror 0
raid1: raid set md1 active with 2 out of 2 mirrors
========================
т.е. два винта которые я добавил стали spare disk
А мне нужно чтоб они стали operational as mirror 2 и 3
соответственно.
В чем грабли в soft-raid HOW-TO про такое не написано. Может сталкивались.
Спасибо за внимание
Ice.
