For example. With one disk, uuid is showed: [root at newc6srv by-uuid]# ls -la /dev/disk/by-uuid/ total 0 drwxr-xr-x 2 root root 80 Mar 28 13:19 . drwxr-xr-x 4 root root 80 Mar 28 13:19 .. lrwxrwxrwx 1 root root 10 Mar 28 13:19 0faf5e22-ff30-4ab8-a9ac-733c593eec40 -> ../../sda1 lrwxrwxrwx 1 root root 10 Mar 28 13:19 37501499-c52d-4a84-9ec8-778adf511ebd -> ../../sda2 but when I add two disks, uuid isn't showed: root at newc6srv by-uuid]# ls -la /dev/disk/by-uuid/ total 0 drwxr-xr-x 2 root root 80 Mar 28 13:19 . drwxr-xr-x 4 root root 80 Mar 28 13:19 .. lrwxrwxrwx 1 root root 10 Mar 28 13:19 0faf5e22-ff30-4ab8-a9ac-733c593eec40 -> ../../sda1 lrwxrwxrwx 1 root root 10 Mar 28 13:19 37501499-c52d-4a84-9ec8-778adf511ebd -> ../../sda2 [root at newc6srv by-uuid]# ls -la /dev/sd* brw-rw---- 1 root disk 8, 0 Mar 28 13:19 /dev/sda brw-rw---- 1 root disk 8, 1 Mar 28 13:19 /dev/sda1 brw-rw---- 1 root disk 8, 2 Mar 28 13:19 /dev/sda2 brw-rw---- 1 root disk 8, 16 Mar 28 13:19 /dev/sdb brw-rw---- 1 root disk 8, 17 Mar 28 13:19 /dev/sdb1 brw-rw---- 1 root disk 8, 32 Mar 28 13:19 /dev/sdc brw-rw---- 1 root disk 8, 33 Mar 28 13:19 /dev/sdc1 and dmesg: sd 2:0:0:0: [sda] Assuming drive cache: write through sda: sd 3:0:0:0: [sdb] 536870912 512-byte logical blocks: (274 GB/256 GiB) sd 3:0:0:0: [sdb] Write Protect is off sd 3:0:0:0: [sdb] Mode Sense: 61 00 00 00 sd 3:0:0:0: [sdb] Cache data unavailable sd 3:0:0:0: [sdb] Assuming drive cache: write through sd 3:0:0:0: [sdb] Cache data unavailable sd 3:0:0:0: [sdb] Assuming drive cache: write through sdb: sda1 sda2 sd 2:0:0:0: [sda] Cache data unavailable sd 2:0:0:0: [sda] Assuming drive cache: write through sd 2:0:0:0: [sda] Attached SCSI disk sd 4:0:0:0: [sdc] 536870912 512-byte logical blocks: (274 GB/256 GiB) sd 4:0:0:0: [sdc] Write Protect is off sd 4:0:0:0: [sdc] Mode Sense: 61 00 00 00 sd 4:0:0:0: [sdc] Cache data unavailable sd 4:0:0:0: [sdc] Assuming drive cache: write through sd 4:0:0:0: [sdc] Cache data unavailable sd 4:0:0:0: [sdc] Assuming drive cache: write through sdc: sdb1 sd 3:0:0:0: [sdb] Cache data unavailable sd 3:0:0:0: [sdb] Assuming drive cache: write through sd 3:0:0:0: [sdb] Attached SCSI disk sdc1 sd 4:0:0:0: [sdc] Cache data unavailable sd 4:0:0:0: [sdc] Assuming drive cache: write through sd 4:0:0:0: [sdc] Attached SCSI disk Then, how can I obtain these uuids?? -- CL Martinez carlopmart {at} gmail {d0t} com
