Sveiki, nulėkė debian servas, su LVM, o po juo XEN virtualios mašinos.
Turiu backupą su Norton Ghost, bet jis nesupportina LVM ir atkuria kaip
paprastas particijas taigi gaunu:
# /sbin/fdisk -l
Warning: omitting partitions after #15.
They will be deleted if you save this partition table.

nuo 1 iki 10 yra sisteminės particijos var, home, tmp, usr, swap,
tereikėjo pa'editint GRUB, fstab ir sistema pakilo.
/dev/vg00/root / ext3

/dev/sda5 / ext3

Svarbiausiam man ši mašina:
# cat /etc/xen/oracle
name = "oracle"
uuid = "cafff27f-362b-866f-53f7-1f3571fcb665"
maxmem = 1024
memory = 1024
vcpus = 2
bootloader = "/usr/bin/pygrub"
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
#vfb = [ "type=vnc,vncdisplay=1,vncpasswd=oracle" ]
vfb = [ ]
# fix the lagging mouse in VNC
#usbdevice = 'tablet'
disk = [ "phy:/dev/vg00/oracle.xen-disk,xvda,w",
"phy:/dev/vg00/oracle.xen-swap,xvdb,w" ]
vif = [ "mac=00:16:3e:2f:10:e3,bridge=xenbr0" ]
# tail -20 /etc/lvm/archive/vg00_00010.vg:
oracle.xen-disk {
id = "RwCJVW-ik57-PJNz-1uRD-k3Ik-xoqb-sQ06fu"
status = ["READ", "WRITE", "VISIBLE"]
segment_count = 1
segment1 {
start_extent = 0
extent_count = 2240 # 70 Gigabytes
type = "striped"
stripe_count = 1 # linear
stripes = [
"pv0", 688
]
}
}
Pagal šitą sprendžiu, kad man reikalinga particija yra 70GB, taigi -
"/dev/sda11", tačiau:
# mount -v -t ext2 /dev/sda11 /mnt/
mount: wrong fs type, bad option, bad superblock on /dev/sda11,
missing codepage or other error
# dmesg | tail
hfs: unable to find HFS+ superblock
hfs: unable to find HFS+ superblock
hfs: unable to find HFS+ superblock
VFS: Can't find an ext2 filesystem on dev sda11.
Bandysiu drožt tą particiją su ext2 recovery toolsais, šiuo metu sukasi
http://www.diskinternals.com/linux-recovery/. Bet labiau norėtųsi kaip
nors pakišti tą particiją XEN'ui vietoj naudotos LVM, kad jis
užsikrautų, gal užtektų ką nors gudraus parašyti čia?
disk = [ "phy:/dev/vg00/oracle.xen-disk,xvda,w", "phy:/dev
Gal eina nesudėtingai atgal surankioti LVM sistemą?
Gal koks geresnis toolsas recoverinimui yra?
Labai laukiu pasiūlymų, Dėkui =]
