Server says no disk space but there is!

[digideus]

ok, long story short...

one of our servers had a power cut and ever since, its telling the users that they have no disk space on the file shares to save files.  they can open files and access the internet through the gateway fine, but its showing that the file share drives are full.

I checked the available disk space with df -h and here is the output

Code: [Select]

Filesystem      Size  Used Avail Use% Mounted on
udev            3.9G  4.0K  3.9G   1% /dev
tmpfs           799M  2.1M  797M   1% /run
/dev/dm-0       917G   53G  817G   7% /
none            4.0K     0  4.0K   0% /sys/fs/cgroup
none             50M     0   50M   0% /run/lock
none            3.9G   14M  3.9G   1% /run/shm
none            100M  4.0K  100M   1% /run/user
/dev/sda1       236M  235M     0 100% /boot

/dev/sda1 is nearly full.  ive seen elsewhere that there is a potential bug in the ubuntu installer that could cause this as well as a cure by resizing the partition, but im not sure thats the cause of my problem as I am trying to access the shares on /dev/dm-0 (where the share folders are under the samba folder), where there is a "rightous" amount of free space   im using 54GB up but i have over 800GB free (its a 1TB disk)

as an aside, I checked the partitions with fdisk -l thinking that there may be a reason for it, and the output is below

...so, am i right in thinking that the reason its saying its full is because /dev/sda1 is full?  Surely thats the linux partition on the disk and its size shouldnt effect the ability to access shares to clients on my network.   (Please correct me if im wrong.)

Anyway, there are posts on here already about the disk space problem when using the "erase all disk" option in the zentyal installer so I wont go into it here, but im concerned about the fdisk "vaild partition table" errors its throwing up.  My fear is that I will resize the sda1 partition but the partition table has been ganked by the power cut and I will be causing more problems than I solve.

anyone?

Hi,

nearly all Linux distros I know get problems if ANY partition runs full...

you should try to uninstall the oldest (one or two) kernel and repair your deb-database.

Afterwards everything should be ok.

Other way is to grow the /boot partition (if this is an option)
