as you know , LV use the whole PV as one big space. so i don't know whether a file is in that PV(/dev/sdb1) or not. how can i cp them? what i want to do is copy all the files in one PV (/dev/sdb1) to the other PV(/dev/sdc1 or /dev/sdd1) automaticly. then i delete that PV(/dev/sdb1) from the VG and change the wrong disk. after that i add the PV(/dev/sdb1) to the VG again. > > here is 'df' information: > > > > /dev/mapper/nicvg-niclv 2.0T 774G 1.2T 40% /ftproot > > > > and here is 'pvscan' information: > > > > ftp:~# pvscan > > /dev/hda: open failed: No medium found > > PV /dev/sdb1 VG nicvg lvm2 [838.09 GB / 0 free] > > PV /dev/sdc1 VG nicvg lvm2 [558.72 GB / 0 free] > > PV /dev/sdd1 VG nicvg lvm2 [558.72 GB / 0 free] > > Total: 3 [1.91 TB] / in use: 3 [1.91 TB] / in no VG: 0 [0 ] > > > > the unstable PV is /dev/sdb1 > > > > i want to move data from /dev/sdb1 to the reset PV such as > /dev/sdc1 > > and /dev/sdd1. > > i think the disk space is enough . > > but when i use command 'pvmove -v /dev/sdb1' i got wrong info: > > > > ftp:~# pvmove -v /dev/sdb1 > > Finding volume group "nicvg" > > No extents available for allocation > > > > my question is : > > the reset of disk space is 1.2TB > > but why 'pvscan' say free space is zero? > > why i can't move data? > > how can i solve the problem? > > > > don't say add another disk to the server. i had added 10 > disks to it > > and there is no space to plug even one. > > > -- > Paolo Alexis Falcone > [EMAIL PROTECTED] > >
