 Re: JFS on 5.2 Hi, yes, JFS2 has this option now. it works if I recall correctly by keeping track of the PP's that are changing in a LV since the snapshot was taken. if a PP is changed after the snapshot was taken, the previous contents of the PP are first copied to a special logical volume. I saw it in a course i attended recently but haven't used it yet. Tom. "Michael E.

| Re: JFS on 5.2 Snapshot is a concept about LVM. It redirect all Output activities to a temp area, and maintain a static image. It's none about JFS. So IBM say, Decrease the activity of a LV before snapshot. If there is a large mount acts , the file system may be inconsistent. The most important the transcation data is inconsitent.
