sda1 size ~ 21.5 G
but using df: # df -kh Filesystem Size Used Avail Use% Mounted on /dev/sdb6 7.7G 5.6G 1.8G 77% / tmpfs 1014M 0 1014M 0% /dev/shm /dev/sda1 190M 5.6M 175M 4% /mnt/sda1
sda1 size = 190M

df comes from the file system rather than the partition. is it possible that the sda1 partition was resized but not reformatted?
if you can stand to lose the data, can you reformat the file system? do you then get the expected size?
my problem is I dont know what happened, it occurred during a botched attempt at using the f10liveinstall cd to install (but backed out) It wasnt my intention to do anything to sda1 ( my target for install was sdb6) but somehow it clobbered sda1 contents, as seen by df, size 190M only 0.19G
I dont know what that liveinstall attempt actually did but the _size_ as seen by fdisk is original size~21G so this tells me there was no resizing of the partition but df says size greatly reduced to 190M=0.19G
I am now leery of doing anything until i understand what fdisk, df tell me I suppose my only choice now is to go ahead and reformat

Or just try "resize2fs /dev/sda1" to resize the filesystem to the size of
the underlying >partition.

I will check out info or man page on resize2fs, thanks

Aren't the "Blocks" listed from fdisk 512 and not 1024? Your numbers would agree quite nicely if so.
Stephen Berg
I dont think that is correct. I dont know exact def of blocks but cyls*8225280bytes ~ 21G
this also checks well on my sdb6 where i am now booted up in my fc5copy /dev/sdb6 1302 2321 8193118+ 83 Linux (2321-1302)*8225280= 8381560320 bytes
Any other explanations as to how size reported by fdisk not same as size from df?
