I have ubuntu 12.10 server, used mostly as fileserver + router. Some times ago it starts behave very strange, for example file transfer from samba server via 1GB/s link becomes very slow(less than 1MB/s)
After some research and play with network, i found that I have 100% of my / partition usage.
Filesystem Size Used Avail Use% Mounted on /dev/md1 3.1G 3.1G 0 100% / /dev/sda1 105M 144k 104M 1% /boot/efi /dev/md2 52G 1.5G 48G 3% /usr /dev/md4 52G 13G 37G 26% /home /dev/md5 21G 181M 20G 1% /tmp /dev/md3 155G 824M 147G 1% /var /dev/md6 21G 437M 20G 3% /var/log
It's a problem, and I think to solve it by moving /lib (2.3G) folder to another directory, and mount it at startup. System is installed on software raid0, so, repartitioning will be very difficult, as I consider.
- Is it like a root of network problems?
What problems will I face if I tried to do smth like rsync
- Can I merge
/home/libcontents and then mount latter to
P.S. I wonder, how it occured. When I'm partitioning my disk, I thought, that all programms will be instaled at /home, or at user folders, which i made big enought… Where can I read about what partitions are used for what programms?
edited: At site I found:
"The directories /bin, /lib, and /etc should never be separate partitions! At boot time, only / is mounted initially. The init program needs to access files in /etc and the bootup scripts need access to commands in /bin, which may depend on files in /lib. Kernel modules required to complete the boot process are also kept in /lib. "
So, i can't move
/lib to another partition.
Can I clear it or smth else?
