Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

i'm running a server with debian stable :

Linux myhostname 2.6.32-5-xen-amd64 #1 SMP Tue Mar 8 00:01:30 UTC 2011 x86_64 GNU/Linux

It is running a nginx, mail server,ftp server and a mysql database.

This morning postfix complained it''s running out of space, so I double checked the free storage and it is as such

root@myhostname:# cat /etc/fstab 
/dev/xvda1 /     ext3    defaults 1 1
/dev/xvda2 /mnt  ext3    defaults 0 0
/dev/xvda3 swap  swap    defaults 0 0
none       /proc proc    defaults 0 0
none       /sys  sysfs   defaults 0 0


root@myhostname:# cat /etc/mtab
/dev/xvda1 / ext3 rw 0 0
tmpfs /lib/init/rw tmpfs rw,nosuid,mode=0755 0 0
proc /proc proc rw,noexec,nosuid,nodev 0 0
sysfs /sys sysfs rw,noexec,nosuid,nodev 0 0
udev /dev tmpfs rw,mode=0755 0 0
tmpfs /dev/shm tmpfs rw,nosuid,nodev 0 0
devpts /dev/pts devpts rw,noexec,nosuid,gid=5,mode=620 0 0
/dev/xvdf /mnt ext4 rw 0 0

So "/dev/xvdf" is a big hdd (500GB) mounted on /mnt and it is where all the stuff related to the webservice is stored, "/dev/xvda1" instead is mounted in the root filesystem and it is an amazon aws standard image ami, 8GB, both of them should have enough free space but:

root@myhostname:# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/xvda1           1008M 1008M     0 100% /
tmpfs                 306M     0  306M   0% /lib/init/rw
udev                  286M   32K  286M   1% /dev
tmpfs                 306M     0  306M   0% /dev/shm
/dev/xvdf             493G  1.1G  467G   1% /mnt

root@myhostname:# fdisk -l /dev/xvda1
Disk /dev/xvda1: 8589 MB, 8589934592 bytes

I'm pretty sure that /dev/xvda is 8GB capacity but for some reason the system sees only 1GB and it is now entirely filled, any ideas why?

Try resize2fs to expand filesystem. As it's AWS, it's good idea to snapshot instance first :-)

Thanks for the answer, it worked like a charm!I'am struggling with the syntax highlighter of serverfault.com but the output of the command is: root@myhostname:~# resize2fs /dev/xvda1 resize2fs 1.41.12 (17-May-2010) Filesystem at /dev/xvda1 is mounted on /; on-line resizing required old desc_blocks = 1, new_desc_blocks = 1 Performing an on-line resize of /dev/xvda1 to 2097152 (4k) blocks. The filesystem on /dev/xvda1 is now 2097152 blocks long. So the filesystem has been properly resized,i would also raccomend the tune2fs utility for those jobs. –  user145634 Nov 15 '12 at 14:19
