I've rent a new server by dedibox.fr and the ubuntu server version is tunned by the dedibox team... On the Ubuntu Server 9.04 64bit/english version, there's a locale configuration issue. whenever you do a aptitude update or run the 'locale' command you get a warning like this : thomas@sd1:~$ locale locale: Cannot set LC_CTYPE to default locale: No such file or directory locale: Cannot set LC_MESSAGES to default locale: No such file or directory locale: Cannot set LC_ALL to default locale: No such file or directory LANG=en_US.ISO-8859-15 LANGUAGE=en_US:en:en_GB:en LC_CTYPE="en_US.ISO-8859-15" LC_NUMERIC="en_US.ISO-8859-15" LC_TIME="en_US.ISO-8859-15" LC_COLLATE="en_US.ISO-8859-15" LC_MONETARY="en_US.ISO-8859-15" LC_MESSAGES="en_US.ISO-8859-15" LC_PAPER="en_US.ISO-8859-15" LC_NAME="en_US.ISO-8859-15" LC_ADDRESS="en_US.ISO-8859-15" LC_TELEPHONE="en_US.ISO-8859-15" L...

On the dev server I spoke previously, we add 2 hard drives of 500GB in order to have 500GB in RAID1 as a network storage. Here is the setup procedure: Check the disk sudo fdisk -l thomas@dev:~$ sudo fdisk -l Disk /dev/sda: 82.3 GB, 82348277760 bytes 255 heads, 63 sectors/track, 10011 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00059bfb Device Boot Start End Blocks Id System /dev/sda1 * 1 36 289138+ fd Linux raid autodetect /dev/sda2 37 218 1461915 fd Linux raid autodetect /dev/sda3 219 826 4883760 fd Linux raid autodetect /dev/sda4 827 10011 73778512+ fd Linux raid autodetect Disk /dev/sdb: 82.3 GB, 82348277760 bytes 255 heads, 63 sectors/track, 10011 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x000d96f2 Device Boot Start End Blocks Id System /dev/sdb1 * ...

Today, one of the developer of 123Monsite.com mess up with one server, and this lead to this : They configure fake hardware on the mother board while it's a software raid... noticing it didn't work, they remove a drive to boot on a degraded raid... and try to find what's wrong... that's when I interrupt the massacre this lead to this : the partitions of the removed drive was marked as deleted (even if it has been replugged and fake-hardware disabled) : thomas@dev:~$ sudo mdadm --query --detail /dev/md3 /dev/md3: Version : 00.90 Creation Time : Thu Sep 4 23:15:23 2008 Raid Level : raid1 Array Size : 73778432 (70.36 GiB 75.55 GB) Used Dev Size : 73778432 (70.36 GiB 75.55 GB) Raid Devices : 2 Total Devices : 1 Preferred Minor : 3 Persistence : Superblock is persistent Update Time : Mon Aug 10 22:45:33 2009 State : clean, degraded Active Devices : 1 Working Devices : 1 Failed Devices : 0 Spare Devices : 0 UUID : 6c7f5b4f:27e96317:a44ec9ef:2b057faa Events : 0.29...
