Hi all, After updating kernel with yum (now is 2.6.17-1.2139_FC5 #1 SMP Fri Jun 23 12:40:11 EDT 2006 x86_64 x86_64 x86_64 GNU/Linux) I see some strange behaviours. Some of them I solved, but I see this: fdisk -l Disk /dev/hda: 100.0 GB, 100030242816 bytes 255 heads, 63 sectors/track, 12161 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 1 382 3068383+ 12 Compaq diagnostics /dev/hda2 383 1657 10241437+ 7 HPFS/NTFS /dev/hda3 2874 12161 74605860 5 Extended /dev/hda4 1658 2873 9767520 83 Linux /dev/hda5 2874 5364 20008926 83 Linux /dev/hda6 * 5365 5402 305203+ 83 Linux /dev/hda7 5403 5663 2096451 82 Linux swap / Solaris /dev/hda8 5664 5788 1004031 b W95 FAT32 /dev/hda9 5789 12161 51191091 8e Linux LVM Partition table entries are not in disk order Disk /dev/dm-0: 16.1 GB, 16106127360 bytes 255 heads, 63 sectors/track, 1958 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/dm-0 doesn't contain a valid partition table Disk /dev/dm-1: 10.7 GB, 10737418240 bytes 255 heads, 63 sectors/track, 1305 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/dm-1 doesn't contain a valid partition table Disk /dev/dm-2: 11.3 GB, 11366563840 bytes 255 heads, 63 sectors/track, 1381 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/dm-2 doesn't contain a valid partition table What are this /dev/dm that I see? I didn't have nothing configured like mirror software or raid. Tnx Ambrogio
