in addition to shrinking the partition
---from man resize_reiserfs
SYNOPSIS
resize_reiserfs [ -s [+|-]size[K|M|G] ] [ -j dev ] [ -fqv ] device
DESCRIPTION
The resize_reiserfs tool resizes an unmounted reiserfs file system. It
enlarges or shrinks an reiserfs file system located on a device....
If the -s option is not specified, the filesystem will
be resized to fill the given device.
If you wish to shrink a reiserfs partition, first use resize_reiserfs
to shrink the file system. You may then use cfdisk(8) to shrink the
device. When shrinking the size of the device, make sure you do not
make it smaller than the reduced size of the reiserfs filesystem.
--- end man page---
I had thought that the size of a filesystem was just the amount
of stuff in there as given by df in the Used column
eg on my external usb /dev/sdc1 which is one large reiserfs partition
[root@bootp ~]# df -kh
Filesystem Size Used Avail Use% Mounted on
...
/dev/sdc1 233G 16G 218G 7% /media/disk-1
so, to me that meant the "size of the filesystem" was given in Used = 16G
but it now seems that is wrong? ie
"size of the filesystem" is actually the entire diskpartition =233G ?
so if I want to shrink dev/sdc1 partition down to 50G
I must
1) shrink the filesystem first using resize_reiserfs also to 50G ?
2) then use cfdisk to shrink the partition to 50G ?
If that is correct, will I retain or lose my current data in that 16G Used?
Is it easier/better to use parted,gparted... for shrinking reiserfs partitions?
there was one recent msg on this list from Mikkel I think
saying parted can handle resizing both partitions and filesystems?
If that is right, it seems less chance for error compared to using two separate tools.
One thing i found on google a 2007 gparted manual
says libreiserfs is needed
Is there any way to get libreiserfs on my fc5 system?
There are apparently live cds,knoppix, gparted,...
will these have everything needed including libreiserfs?
thanks for any help, pointers,....
