i assumed that snapshot is created and you start backing up the snapshot file... > power goes out midway. Will the LV be corrupted? Why/why not? maybe you mean the filesystem? filesystem is on top of LV ... LV is a raw block device just as physical HDD partition... filesystem corrupts but not the partition... corruption begins if write is not completed... which means as long as there is no write activity and power goes off... it will not corrupt your filesystem... for snapshot file.. once created.. it is already in consistent state of a previous state of your filesystem.... > If anyone can point me towards some reference materials, that'd be great. > Thanks! http://www.markus-gattol.name/ws/lvm.html fooler. _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List http://lists.linux.org.ph/mailman/listinfo/plug Searchable Archives: http://archives.free.net.ph
