Re: [linux-lvm] Pvmove fails... No free PE's (and lvextend does not work...)



Well... here is what the problem is right now.:

First I scan all physical disks to determine where I have free space to grow..


pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ACTIVE   PV "/dev/hdo1" of VG "Server" [55.84 GB / 0 free]
pvscan -- ACTIVE   PV "/dev/hdp1" of VG "Server" [28.56 GB / 0 free]
pvscan -- ACTIVE   PV "/dev/hdm1" of VG "Server" [76.28 GB / 0 free]

pvscan -- ACTIVE   PV "/dev/hdl1" of VG "Server" [55.84 GB / 0 free]
pvscan -- ACTIVE   PV "/dev/hdg1" of VG "Server" [55.88 GB / 0 free]
pvscan -- ACTIVE   PV "/dev/hdh1" of VG "Server" [55.88 GB / 0 free]
pvscan -- ACTIVE   PV "/dev/hde1" of VG "Server" [114.44 GB / 38.16 GB free]
pvscan -- ACTIVE   PV "/dev/hdf1" of VG "Server" [57.22 GB / 0 free]
pvscan -- ACTIVE   PV "/dev/hdc1" of VG "Server" [71.53 GB / 0 free]
pvscan -- ACTIVE   PV "/dev/hdd1" of VG "Server" [71.53 GB / 0 free]
pvscan -- ACTIVE   PV "/dev/hdb1" of VG "Server" [4.28 GB / 0 free]
pvscan -- ACTIVE   PV "/dev/hdb3" of VG "Server" [52.88 GB / 0 free]
pvscan -- total: 14 [815.29 GB] / in use: 14 [815.29 GB] / in no VG: 0 [0]

Now I use "lvextend -l +1221 /dev/Server/FTPRoot /dev/hde1" to grow my LV "FTPRoot". It worked fine on my new disk (to wich I also moved the old PE's from the bad disk), but not on this one. What 
can be the problem. Where should I even begin to look?

lvextend -- extending logical volume "/dev/Server/FTPRoot" to 814.56 GB
lvextend -- not enough free/allocatable physical extents to extend logical volume /dev/Server/FTPRoot

Thanks for any help!
