One of the disks got out of space, however other disk is nearly empty. Need suggestions how to transfer biggest folder(/var) to the other disk and mount at /var. For now /var folder was in / partition. Got 90GB unallocated space at /dev/sdb. It's a vmware virtual machine.$df -H resultFilesystem                              Size  Used Avail Use% Mounted onrootfs                                   22G   20G  711M  97% /udev                                     11M     0   11M   0% /devtmpfs                                   425M  398k  425M   1% /run/dev/disk/by-uuid/a8db5cdb-96f3-4497-9   22G   20G  711M  97% /tmpfs                                   5.3M     0  5.3M   0% /run/locktmpfs                                   850M     0  850M   0% /run/shm/dev/sdb1                                11G  980M  8.9G  11% /home$fdisk -l resultDisk /dev/sda: 21.5 GB, 21474836480 bytes255 heads, 63 sectors/track, 2610 cylinders, total 41943040 sectorsUnits = sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x000c0f7fDevice Boot      Start         End      Blocks   Id  System/dev/sda1            2048      194559       96256   82  Linux swap / Solaris/dev/sda2   *      194560    41940991    20873216   83  LinuxDisk /dev/sdb: 107.4 GB, 107374182400 bytes255 heads, 63 sectors/track, 13054 cylinders, total 209715200 sectorsUnits = sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x0002dc8dDevice Boot      Start         End      Blocks   Id  System/dev/sdb1            2048    20482047    10240000   83  Linux
