I've connected a few SCSI-disks to one of my SUN ELC's, running
Linux/SPARC 2.0.35. I've setup an /etc/mdtab with mdcreate so that;
| /dev/md0 raid0,4k,0,1c2518a6 /dev/sdb3 /dev/sdc3
but whenever I run mdadd -a I get the following errors;
| beldaran:~# mdadd -a
| /dev/sdb3: Device or resource busy
| /dev/sdc3: Device or resource busy
Though this is certainly not the case since I can mount and unmount
/dev/sdb3 without problems;
| beldaran:~# mount /dev/sdb3 /mnt
| beldaran:~# umount /dev/sdb3
| beldaran:~#
A strace on the process gives the following;
| open("/dev/md0", O_RDONLY) = 6
| stat("/dev/sdb3", {st_mode=S_IFBLK|0660, st_rdev=makedev(8, 19), ...}) = 0
| ioctl(6, REGISTER_DEV, 0) = -1 EBUSY (Device or resource busy)
| write(2, "/dev/sdb3: Device or resource bu"..., 35/dev/sdb3: Device or resource
|busy) = 35
| stat("/dev/sdc3", {st_mode=S_IFBLK|0660, st_rdev=makedev(8, 35), ...}) = 0
| ioctl(6, REGISTER_DEV, 0) = -1 EBUSY (Device or resource busy)
| write(2, "/dev/sdc3: Device or resource bu"..., 35/dev/sdc3: Device or resource
|busy) = 35
The /dev/md0 device is as follows;
| brw-rw---- 1 root disk 9, 0 May 24 19:39 /dev/md0
And /proc/mdstat gives;
| Personalities : [1 linear] [2 raid0]
| read_ahead not set
| md0 : inactive
| md1 : inactive
| md2 : inactive
| md3 : inactive
Any help with this problem would be greatly appreciated. Thanks,
Jonas
