Hello, when i used command to chceck disks df -h a get Filesystem Size Used Avail Use% Mounted on udev 16G 0 16G 0% /dev tmpfs 3.2G 676K 3.2G 1% /run /dev/sda1 915G 58G 811G 7% / tmpfs 16G 0 16G 0% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock /dev/sdb1 915G 1.1M 869G 1% /mnt tmpfs 3.2G 0 3.2G 0% /run/user/0 I know that is sda ana sdb, but not sure about other filesystem? Because i think that when i created dedicated server, there was only udev and tmpfs once, but now i can see more. In my ispconfig panel i can see only udev tmpfs and sda and sdb Specialy i dont know that is /dev/shm Is possible to found usage or remove them? Thank you
they're temporary virtual file systems. they don't use any disk space, they use ram. any data in them is lost in a reboot. they're used as dynamic device manager (udev) or for temporary files you can delete them, though the files may be needed for running services/applications/devices. so expect problems if you do. if you do have problems, they'll be solve by a reboot, when any necessary temporary files/folders will be recreated. google udev or tmpfs for more information on them than you could possibly ever want to know.
