Re: PVDISPLAY & gnome disk utility size of disk not same, even though UUID is the same?

GiB is not the same as GB. GB = 1000 x 1000 x 1000. GiB = 1024 x 1024 x 1024.

Your 26843545600 byte "disk" is actually 25GiB (26843545600/1024/1024/1024). Since that's the size of the entire disk and the default size for /boot is 1GiB, your LVM PV is 25GiB - 1GiB = 24GiB.


thanks!

Re: Yum Update - Could not retrieve mirrorlist error 14. With working DNS...?

Hello okay thanks. 1) I understand that NAT is a dead-end, no? "The version of curl that we ship as part of the distro works perfectly with all the CentOS public mirrors that are available." 2) this rules out a cipher problem, correct? "You are not using the bridged mode that you think you are (and ...
