LVM should handle this. If the snapshot device goes away, then just vgreduce it on the reboot. Trying to retrofit snapshot into existing systems is far easier if you can use ramdisk, esata-hdd, usb-hdd, usb-stick because most systems have allocated all space and rather than struggling through trying to compact and reduce VG, LV, PV, partition, filesystem to gain space it is much easier to use other devices. And again this is something that LVM should be able to handle. > If there is only snapshot, you can recover it, if some operation placed > here part of another volume, you will lose data. > part of another volume placed where? on the snapshot? I don't understand this part. Regards, Gerry
