mdadm update
Hallo zusammen!
Heute habe ich gesehen, dass mdadm aktualisiert wurde.
Dpgk meinte beim upgrade:
WARNING! If you are using hard disks which have a md superblock from an │
earlier installation in a different RAID array, you MUST zero the │
superblock before activating the autostart feature. │
│
For doing this, do not start the RAID devices automatically and zero the │
superblock (mdadm --zero-superblock /dev/xxx). You can then further use │
'dpkg-reconfigure mdadm' to activate the autostart feature. │
Natürlich haben meine Disks einen superblock, aber "early installation" ... betrifft das auch die vorletzte Version?
Ich nehme an, dass das nur Leute betrifft welche von einer Ur-Version her kommen und mdadm jetzt plötzlich nutzen und allenfalls schrott im superblock stehen haben.
und weiter:
If RAID devices are started automatically, all RAID devices are │
discovered and assembled automatically at system startup. This option │
should only be used if the md driver is compiled as a module. If it is │
compiled into your kernel, the automatic startup will be performed at │
boot time by the kernel and therefore you should not choose this option. │
Da bin ich mir jetzt gerade etwas unsicher geworden.
Nach einem probehalber restart einer Testmaschine läuft alles noch, in dmesg sind auch keine Fehlermeldung vorhanden.. (mdadm ist allerdings ja wohl nur
das userspace programm...)
Folgend die kernel-config: (2.6.14.2)
#
# Multi-device support (RAID and LVM)
#
CONFIG_MD=y
CONFIG_BLK_DEV_MD=y
CONFIG_MD_LINEAR=m
CONFIG_MD_RAID0=m
CONFIG_MD_RAID1=y
CONFIG_MD_RAID5=m
CONFIG_MD_RAID6=m
CONFIG_MD_MULTIPATH=m
CONFIG_MD_FAULTY=m

Mdadm -V zeigt noch immer dieselbe Version...
So what changed?
Was meint ihr dazu?
Gruess!
