I used to do this with vms=20 that usually get one local disk. But.. This time this host was attached to several existing ovirt (production)=20 lun and anaconda gathered all existing disk (local and lun) into the=20 same VG (lv_home) et formatted them with XFS.... In the webadmin, the domain storage became unvailaible, vms were still=20 up (thankgoodness), but it was impossible to interact with them. If I=20 stopped them, it was impossible to reboot them. If I launch lvs command,=20 some hosts can still see the ovirt LV, but other see only the lv_home=20 while /dev/[idofvms] are still present. So it was my chance that vms were still present, and I began to export=20 them with a tar at file system level so as to import them in a new=20 domain storage. =20 It seems that data are still present because the vms are still running. So my question is really : instead of this difficult export step, is=20 there a way to recover the initial format of the ovirt lun so as to make=20 the lvm index come back on the disk=3F =20 Any help or disaster experience would be much appreciated. =20 --=20 Nathana=C3=ABl Blanchet =20 Supervision r=C3=A9seau P=C3=B4le Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 =09 T=C3=A9l. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet@abes.fr =20 =20 _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users =20
