[sarge] Some troubles with LVM2 over RAID1
Здравствуйте, debian-sparc.
I have:
$ uname -a
Linux bug2 2.4.27-3-sparc64-smp #1 SMP Thu Feb 9 20:32:30 UTC 2006 sparc64 GNU/Linux

/dev/md1: No md super block found, not an md component.
Why?? 8-0
Well, try to create LVM:
$sudo pvscan
PV /dev/md1 VG vgsys lvm2 [11.98 GB / 11.98 GB free]
Total: 1 [11.98 GB] / in use: 1 [11.98 GB] / in no VG: 0 [0 ]
$ sudo vgscan
Reading all physical volumes. This may take a while...
Found volume group "vgsys" using metadata type lvm2
$ sudo pvdisplay

$ sudo lvcreate -n lvusr -L 3G vgsys
striped: Required device-mapper target(s) not detected in your kernel
lvcreate: Create a logical volume
...
Why "striped"?
Can i create LVM2 volumes?
