I have CentOS server with 7 partitions and 2 of them are LVM partitions one is divided as 2 LVM partitions. While working with the production software the disk suddenly gets full in a folder that is stored in one of the LVM partitions that are together in one of the 7 normal partitions. My / partition is only 40G while the /somedir LVM partition is 250G of space, why is the system reporting disk full when the files in the LVM partition grow near the size of the / partition??
the df -h command throws:
/dev/sda2 39G 6,9G 30G 19% / tmpfs 3,9G 1,4M 3,9G 1% /dev/shm /dev/mapper/vgdata-bcks 247G 172G 63G 74% /backups /dev/sda1 485M 310M 151M 68% /boot /dev/mapper/vgusers-home 386G 3,4G 363G 1% /home /dev/sda5 14G 36M 13G 1% /tmp /dev/mapper/vgdata-usrs 247G 30G 205G 13% /usr1 192.168.11.70:/data 2,0T 249G 1,8T 13% /mnt/SATANAS //192.168.11.240/Spooler 233G 57G 177G 25% /mnt/Fiscaldir //192.168.11.223/Catalogos 96G 44G 53G 46% /media/Catalogos //192.168.11.204/compartidos 98G 42G 51G 46% /mnt/Reportes /dev/sdb1 3,7T 31G 3,7T 1% /media/Seagate Backup Plus Drive
sorry it was not formatted before
First try to figure out if there is any error in the partition using “dmesg” command. If you find any error, and if you are not much familiar to fix the issue, a simple reboot may fix the issue.
If it is truly a inode related issue, you may reduce your reserved space. It will give some space and also inode as well. (though it is not recommended for production environment. As soon as possible revert it back to 2% or 3%).
tune2fs -m 0 /dev/sda1 tune2fs 1.41.12 (17-May-2010) Setting reserved blocks percentage to 0% (0 blocks)
Find zero sized or unused files using find command and remove it after analyzing the files.
If possible take backup of the entire file system and create filesystem again using the command,
mkfs.ext4 -i </dev/destination>
to specify the number of inodes and then restore the original contents into this.
I believe you’ve run out of inodes on the partition.
If you do
df -i you will probably find the inode usage is 100%.
