Wrench The problem in the new partition

hi



I created a new partition
Code:
 ls -l /dev/sda*
brw-rw---- 1 root disk 8,  0 Oct 21 12:29 /dev/sda
brw-rw---- 1 root disk 8,  1 Oct 12 11:19 /dev/sda1
brw-rw---- 1 root disk 8, 10 Oct 21 13:50 /dev/sda10
brw-rw---- 1 root disk 8,  2 Oct 12 11:19 /dev/sda2
brw-rw---- 1 root disk 8,  3 Oct 12 11:19 /dev/sda3
brw-rw---- 1 root disk 8,  4 Oct 12 11:19 /dev/sda4
brw-rw---- 1 root disk 8,  5 Oct 12 11:19 /dev/sda5
brw-rw---- 1 root disk 8,  6 Oct 12 11:19 /dev/sda6
brw-rw---- 1 root disk 8,  7 Oct 12 11:19 /dev/sda7
brw-rw---- 1 root disk 8,  8 Oct 12 11:19 /dev/sda8
brw-rw---- 1 root disk 8,  9 Oct 12 11:19 /dev/sda9

does not uuid
Code:
blkid
/dev/sda6: UUID="be917ce9-5fe9-4aaf-9c10-88ce82150b0a" TYPE="ext4"
/dev/sda1: UUID="a56fb069-730e-4fc2-916b-3de5785af7a0" TYPE="ext4"
/dev/sda2: UUID="94e4045a-3e84-442d-8407-a8bbd8b604e2" TYPE="ext4"
/dev/sda3: UUID="1baf1564-ae1c-439d-a501-9cf8a90fdc32" TYPE="ext4"
/dev/sda5: UUID="a8717015-25e5-4a25-8e32-c42d32b1aaf3" TYPE="ext4"
/dev/sda7: UUID="dd0f0f25-6d0d-406a-9105-cb5663a64289" TYPE="swap"
/dev/sda8: UUID="a81d2238-fd2e-4cee-b87f-4e238db4332d" TYPE="ext4"
/dev/sda9: UUID="a6e0ce34-fe76-4999-a4ab-b54fa328f507" TYPE="ext4"

When I make uuid this error
Code:
 tune2fs /dev/sda10 -U 3706d0a7-066b-49f5-b0cc-6803245a70dd
tune2fs 1.41.12 (17-May-2010)
tune2fs: Bad magic number in super-block while trying to open /dev/sda10
Couldn't find valid filesystem superblock.

Code:
 tune2fs -l /dev/sda10
tune2fs 1.41.12 (17-May-2010)
tune2fs: Bad magic number in super-block while trying to open /dev/sda10
Couldn't find valid filesystem superblock.

NAME
pvck - check physical volume metadata SYNOPSIS
pvck [-d|--debug] [-h|--help] [-v|--verbose] [--labelsector] PhysicalVolume [PhysicalVolume...] DESCRIPTION
pvck checks physical volume LVM metadata for consistency. OPTIONS
See lvm for common options. --labelsector sector By default, 4 sectors of PhysicalVolume are scanned for an LVM label, starting at sector 0. This parameter allows you to specify a different starting sector for the scan and is useful for recovery situations. For example, suppose the partition table is corrupted or lost on /dev/sda, but you suspect there was an LVM partition at approximately 100 MB. This area of the disk may be scanned by using the --labelsector parameter with a value of 204800 (100 * 1024 * 1024 / 512 = 204800): pvck --labelsector 204800 /dev/sda Note that a script can be used with --labelsector to automate the process of finding LVM labels.
