Alasdair Kergon	8ef2b021ed	Default stripesize 64k & config file setting for it; ... Clear many compiler warnings (i386) & associated bugs - hopefully without introducing too many new bugs:-) (Same exercise required for other archs.) Default compilation has optimisation - or else use ./configure --enable-debug	2002-12-19 23:25:55 +00:00

AJ Lewis	fccc39a3a7	o Added function find_snapshots to snapshot_manip.c that returns a list ... of snapshots whose origin is the lv passed in. o Used this new function to make lvdisplay properly display all snapshots attached to a origin.	2002-05-08 16:57:46 +00:00
Alasdair Kergon	25b733809a	Merge with text format branch. ... Lots of changes/very little testing so far => there'll be bugs! Use 'vgcreate -M text' to create a volume group with its metadata stored in text files. Text format metadata changes should be reasonably atomic, with a (basic) automatic recovery mechanism if the system crashes while a change is in progress. Add a metadata section to lvm.conf to specify multiple directories if you want (recommended) to keep multiple copies of the metadata (eg on different filesystems). e.g. metadata { dirs = ["/etc/lvm/metadata1","/usr/local/lvm/metadata2"] } Plenty of refinements still in the pipeline.	2002-04-24 18:20:51 +00:00

Joe Thornber	0e32e054df	o add find_cow function.	2002-02-21 10:16:33 +00:00
Alasdair Kergon	b6afcf6458	Remove VG arg from lv_is_cow() and lv_is_origin() - use lv->vg instead.	2002-02-20 19:04:55 +00:00
Joe Thornber	0a9f8bcf97	o First pass at format1 snapshot support.	2002-02-13 11:43:29 +00:00
Joe Thornber	7d68b08028	o First changes to add snapshot support. ... I'm taking a different route from LVM1 here in that snapshots are a seperate entity from the logical volumes, I think of them as an application of an LV (or two lvs rather). As such there is a list of snapshots held against the vg, and there is *not* a SNAPSHOT, or SHAPSHOT_ORG flag in lv->status.	2002-02-12 16:31:31 +00:00
