Re: [linux-lvm] how to remove PV from a VG?

Hi Freddy.

> the subject says it (almost) all, I need to remove three PVs that were added to my VG by mistake (namely /dev/sdi, /dev/sdj and /dev/sdk), I guess you see where the error is. I can access data on previous PVs (yet), but don't know how to remove PVs, there is nothing linke 'pvremove'. I can assure you there is no data (perhaps except signature) on those disks.

vgreduce YourVG /dev/sd[i-k]

- or, if the 3 partitions hold the only empty PVs of YourVG -

vgreduce -a YourVG


> Another question regarding devfs, some time ago a guy had a problem with devfs and 'smart' libs and Heinz pointed him to mailing list archives to look for patches. I did so, too (because I have tha same probs) but didn't find anything regarding this issue, anyone can help me with this?


I don't recall if it was me 8*)

If you refer to the code in tools/lib/pv_read_all_pv.c which tried to
optimize performance while scanning the device special files, you can
comment out lines 103-105 and 107 to fix this.

HTH.
