I vgreduced and everything to remove drives, it seemed working okay, so I exported in preparation to move to another box.<o:p></o:p> Now, I am unable to import it again. I have plugged the drives I removed back in, just in case, however they seem to be not related.<o:p></o:p> <o:p> </o:p> <o:p> </o:p> Im pretty new to lvm, so maybe ive missed something obvious?<o:p></o:p> Ive been googling and reading howto for a couple of hours, ive still no solution (maybe im a noob?). Ive seen some other vgimport related stuff, but not as seemingly simple as this?!?<o:p></o:p> <o:p> </o:p> <o:p> </o:p> Does anybody know why vgimport is saying I have the wrong number of drives?<o:p></o:p> Im 99% sure its wanting 4 drives, but it still isn’t liking me very much.<o:p></o:p> <o:p> </o:p> Alternatively, does anybody know how to get data off this exported vg, so I can at least not loose everything?<o:p></o:p> <o:p> </o:p> <o:p> </o:p> I noticed people were posting lots of info, so I thought I might do the same, just to give a good idea on whats going on<o:p></o:p> <o:p> </o:p> Pvscan results:<o:p></o:p> pvscan -- reading all physical volumes (this may take a while...)<o:p></o:p> pvscan -- inactive PV "/dev/hdg" is in EXPORTED VG "storage_group" [93.12 GB / 0 free]<o:p></o:p> pvscan -- inactive PV "/dev/hdh" is in EXPORTED VG "storage_group" [111.75 GB / 3.16 GB free]<o:p></o:p> pvscan -- inactive PV "/dev/hde" is in no VG [37.27 GB]<o:p></o:p> pvscan -- inactive PV "/dev/hdf" is in no VG [38.35 GB]<o:p></o:p> pvscan -- inactive PV "/dev/hdc" is in EXPORTED VG "storage_group" [111.75 GB / 0 free]<o:p></o:p> pvscan -- inactive PV "/dev/hda3" is in EXPORTED VG "storage_group" [70.88 GB / 0 free]<o:p></o:p> pvscan -- inactive PV "/dev/hdb" is in no VG [38.35 GB]<o:p></o:p> pvscan -- total: 7 [501.64 GB] / in use: 4 [387.67 GB] / in no VG: 3 [113.96 GB]<o:p></o:p> <o:p> </o:p> hde, hdf and hdb were going to be removed.
