| | ===== Mount ===== |
| | |
| | The "mount" command showing only xfs and ext4 file system types (-t xfs,ext4) |
| | |
| | <code bash> |
| | [root@srv01 ~]# mount -t xfs,ext4 |
| | /dev/mapper/vgroot-lvroot on / type xfs (rw,relatime,attr2,inode64,noquota) |
| | /dev/mapper/vgblackusb-lvblackbackups on /mnt/blackusb type ext4 (rw,relatime,data=ordered) |
| | /dev/mapper/vgredusb-lvredbackups on /mnt/redusb type ext4 (rw,relatime,data=ordered) |
| | /dev/mapper/vgroot-lvtmp on /tmp type xfs (rw,relatime,attr2,inode64,noquota) |
