[opensuse] disk size, how is this possible?
two seemingly identical disks (usb enclosure): Disque /dev/sdc : 931,5 GiB dev/sdc1 2048 1953525167 1953523120 931,5G 83 Linux Disque /dev/sdd : 931,5 GiB, /dev/sdd1 2048 1953525163 1953523116 931,5G 83 Linux and same sector size... df -h: /dev/sdd1 917G /dev/sdc1 925G not the same size! mount: /dev/sdd1 on /run/media/jdd/926ae05a-dcd4-4939-8d30-3ef5ed75894e type ext4 (rw,nosuid,nodev,relatime,data=ordered,uhelper=udisks2) /dev/sdc1 on /run/media/jdd/archives-2012 type ext4 (rw,nosuid,nodev,relatime,data=ordered,uhelper=udisks2) same file system, same options any idea? thanks jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

not the same size!

any idea?

No difference in the blocks allocated for root? Though I don't know if that would affect the size that's shown running that command. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

So what? Filesystem size != device size. In the worst case filesystem can even be bigger, although you probably won't be able to use it for a long time in this case, at least for writing.
mount: /dev/sdd1 on /run/media/jdd/926ae05a-dcd4-4939-8d30-3ef5ed75894e type ext4 (rw,nosuid,nodev,relatime,data=ordered,uhelper=udisks2)
/dev/sdc1 on /run/media/jdd/archives-2012 type ext4 (rw,nosuid,nodev,relatime,data=ordered,uhelper=udisks2)
same file system, same options
any idea?
Check *filesystem* size, check reserved space. tune2fs -l, block count and reserved block count. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

as far as I remember, the two of them created with mkfs.ext4 by me (but not at the same date)

The original issue was with different amounts of freespace: df -h: /dev/sdd1 917G /dev/sdc1 925G If freshly formatted they should be the same. Once you start using a filesystem the freespace starts to change. I don't know if "rm -rf /mnt_point" will bring the 2 back into alignment. So, what is the usage history of the 2 filesystems? Both virgin? One virgin, one used and then content deleted? Greg -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

most of the time, contents often deleted, but there are no hidden files (first thing I tested) and the difference is pretty large there is one block difference that can come from building difference, but going from 917 to 925 Gb... *7Gb* difference... jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
