Hi all,
I'm having problems to create/resize an lv up to 1T (well I can't reach 300G), my system is a CentOS 5.1 x86_64 on a Dell 2950 with 6x500G SATA (RAID5 to aprox. 2.5T)
[root@Mugello ~]# fdisk -l
Disk /dev/sda: 2497.7 GB, 2497791918080 bytes 255 heads, 63 sectors/track, 303672 cylinders Units = cilindros of 16065 * 512 = 8225280 bytes

When I try to create a 1T lv it gives me this error:
[root@Mugello ~]# lvcreate -L1T -nstor sys device-mapper: reload ioctl failed: Argumento inválido Failed to activate new LV.
and on /var/log/messages I had this:
Dec 6 08:31:27 Mugello kernel: device-mapper: table: device 8:2 too small for target Dec 6 08:31:27 Mugello kernel: device-mapper: table: 253:4: linear: dm-linear: Device lookup failed Dec 6 08:31:27 Mugello kernel: device-mapper: ioctl: error adding target to table
the lv is created:
[root@Mugello ~]# lvs LV VG Attr LSize Origin Snap% Move Log Copy% root sys -wi-ao 4,00G stor sys -wi-d- 1,00T swap sys -wi-ao 2,00G usr sys -wi-ao 5,00G var sys -wi-ao 5,00G
but is unusable:
[root@Mugello ~]# mkfs -t ext3 /dev/sys/stor mke2fs 1.39 (29-May-2006) Could not stat /dev/sys/stor --- Arquivo ou diretório não encontrado
The device apparently does not exist; did you specify it correctly? [root@Mugello ~]# ls -la /dev/mapper/ total 0 drwxr-xr-x 2 root root 160 Dez 6 09:02 . drwxr-xr-x 12 root root 4220 Dez 6 07:43 .. crw------- 1 root root 10, 63 Dez 6 07:43 control brw-rw---- 1 root disk 253, 0 Dez 6 07:43 sys-root brw-rw---- 1 root disk 253, 4 Dez 6 09:02 sys-stor brw-rw---- 1 root disk 253, 3 Dez 6 07:43 sys-swap brw-rw---- 1 root disk 253, 1 Dez 6 07:43 sys-usr brw-rw---- 1 root disk 253, 2 Dez 6 07:43 sys-var [root@Mugello ~]# mkfs -t ext3 /dev/mapper/sys-stor mke2fs 1.39 (29-May-2006) mkfs.ext3: Device size reported to be zero. Invalid partition specified, or partition table wasn't reread after running fdisk, due to a modified partition being busy and in use. You may need to reboot to re-read your partition table.
If I try with a small size (less than 300G) it works well:
[root@Mugello ~]# lvcreate -L100G -nstor sys Logical volume "stor" created [root@Mugello ~]# lvs LV VG Attr LSize Origin Snap% Move Log Copy% root sys -wi-ao 4,00G stor sys -wi-a- 100,00G swap sys -wi-ao 2,00G usr sys -wi-ao 5,00G var sys -wi-ao 5,00G
What can I try to do to create an lv with 1T??
Thanks in advance,
Antonio.
