trying to format a partition as ext4 getting following error [root@f14 ~]# mkfs.ext4 /dev/sdc7 mke2fs 1.41.12 (17-May-2010) mkfs.ext4: No such device or address while trying to determine filesystem size [root@f14 ~]# I did this same command earlier today and it worked. Since then, I made some kind of error copying to that partition, after it was mounted to /mnt/sdc7. So I was trying to reformat. Also, now if I try to mount it I can't even see what is in it: [root@f14 ~]# mount /dev/sdc7 /mnt/sdc7 mount: /dev/sdc7 is not a valid block device This must be newbie stuff, but I am lost. mount shows sdc9 for example /dev/sdc9 on /grubp type ext3 (rw) but fdisk -l shows only sda, sdb, nothing for sdc df -kh does show sdc9, nothing for sdc7 root@f14 ~]# df -kh Filesystem Size Used Avail Use% Mounted on /dev/sda8 17G 8.1G 7.5G 52% / tmpfs 1007M 444K 1006M 1% /dev/shm /dev/sdc9 16M 1.5M 13M 11% /grubp /dev/sda3 21G 9.2G 11G 48% /media/54c84c0a-040b-43bd-8887-202519baaae2_ /dev/sda6 8.1G 7.0G 1.1G 87% /media/rootusb6_ /dev/sda7 16G 7.3G 7.4G 50% /media/c2f44d00-09e6-45b2-9a14-a0a765716005_ /dev/sda2 21G 7.5G 13G 38% /media/rootusb2_ /dev/sda1 24G 18G 5.8G 76% /media/rootusb_ [root@f14 ~]# Jack -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
