| |
Hello,
I'm using a machine that supports SATA hotplug and with and Intel ESB2 (Fake)Raid controller. I've configured a raid1 (mirror) array using dmraid, that is made of /dev/sda and /dev/sdb, and seen by the OS as /dev/mapper/isw_xxxxxxx_RAID1
My problem is that when I unplug and replug a disk, it is assigned a new name (/dev/sdc first time as this is the first name available), and so it is no more considered as being part of the RAID array.
Is this an expected behavior ? Is there a way (using dmraid/dmsetup) to instruct kernel of the changes ?
It seems that udev can get events from device-mapper, from Documentations/device-mapper/dm-xxxx.txt, but I don't really see how to use this to notify of a disk change in the array...
Regards, Paul
