I successfully made a logical volume out of four disks. I am now attempting to do the same to another four disks on the same system. "fdisk -l" shows a similar result for each of the new four Disk /dev/sdk1: 2000.3 Gb, 2000398923016 bytes 255 heads, 63 sectors/track, 243201 cylinders Units cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdk1 1 243201 1953512001 83 Linux parted sees them as Model: ATA WDC WD20EAD5-98R (scsi) Disk /dev/sdk: 2000GB Sector size (logical/physical): 512B/512B partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 2000Gb 2000GB primary but mkfs doesn't work mkfs -t ext3 /dev/sdk1 make2fs 1.39 (29-May-2006) Could not stat /dev/sdk1 --- No such file or directory Same results with "mke2fs -j" cat /proc/partitions shows for the disks that worked: 8 96 1953514584 sdg 8 97 1953512001 sdg1 for the disks that don't work: 8 112 1953514584 sdk parted is version 1.8.1-27.el5. I have the system completely updated. 2.6.18-238.9.1.el5xen I understand that parted is sometimes a problem. Should I download gparted? -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
