All drives are part of 'fileshare/lv_fileshare',
which only has 400GB of data on it at the moment;
The FILESYSTEM which you built in lv_fileshare
has 400GB of data in a 2TB filesystem, probably.
The lv_fileshare LV itself is around 2TB, so it won't
fit on a 1TB drive. You would need to first reduce
the size of the filesystem, using resize2fs or similar,
then reduce the size of the LV using lvreduce, then
move it using pvmove.
A tip - reduce the filesystem 10%-20% smaller than
the LV will be on - making it about 800GB, to make sure
it will fit on a 1000GB volume. A 1000GB filesystem
won'yt necesarily fit on a 1000GB volume because of
rounding, GB versus GiB, etc. After resizing the LV,
you can resize2fs it to fill the volume.

reflected in the PFREE columns of the PVS output. Is there an easy
way to force the LVM to rescan it's allocation unit or would I have
to remove the drives and re-insert them into the LVM?

OK according to that both are full of an LV
called "lv_fileshare". Try mounting that and
see what, if anything, is on it. Don't remember
creating that? Try history | grep -10 lv_fileshare
for a reminder.

Hello List,
I have a fileserver that is driving me nuts at the moment. Setup:
4x 1TB HDD's
1x 320GB HDD
They all have the same partition layout:
512MB Swap, rest is LVM data.
The LVM only contains ~400GB of data, but 2 of the TB drives
report having 0 free PFree's:
PV VG Fmt Attr PSize PFree
/dev/mapper/cryptsda fileshare lvm2 a- 931.03G 0
/dev/mapper/cryptsdb fileshare lvm2 a- 931.03G 0
/dev/mapper/cryptsdc fileshare lvm2 a- 297.61G 297.61G
/dev/mapper/cryptsdd fileshare lvm2 a- 931.03G 633.42G
/dev/mapper/cryptsde lvm2 -- 931.04G 931.04G
I've successfully managed to remove SDE from the LVM, but I need
to move the data off SDD onto either SDA or SDB. When the whole
system is mounted it properly reports having 2.1TB of free space
(931 * 2 + 297). Is there an easy way to fix this issue?
