Mounting ISO images on UNIX and Linux
This is a simple post providing details on how to mount and unmount an ISO CD-ROM image as a local file system on various UNIX platforms.
On Solaris
- To mount:
# lofiadm -a /<file.iso>
This will create device file/dev/lofi/1
# mount -F hsfs -o ro /dev/lofi/1 /<mountpoint>
- To unmount:
# umount /<mountpoint> # lofiadm -d /dev/lofi/1
On RedHat/Linux
- To mount:
# mount -t iso9660 /<file.iso> /<mountpoint> -o loop
- To unmount:
# umount /<mountpoint>
On HP-UX
- To mount:
# nohup pfs_mountd & # nohup pfsd & # pfs_mount -o xlat=UNIX <file.iso> /<mountpoint>
- To unmount
# pfs_umount /
Subsequently, kill the following processes:- pfs_mountd
- pfsd
- pfs_mountd.rpc
- pfsd.rpc
On IBM AIX
- To mount:
- Build a logical volume (the size of an ISO image, better if a little bigger)
- Create an entry in /etc/filesystem using that logical volume (LV), but setting its Virtual File System (V'S) to be cdrfs
- Create the mount point for this LV/ISO
- Copy the ISO image to the LV using dd
- Mount and work on it like a mounted CD-ROM
The entry in /etc/filesystem should look like:
/IsoCD: dev = /dev/lv09 vfs = cdrfs mount = false options = ro account = false
- To mount (example 2):
Mount ISO image as a cdrfs filesystem.
# loopmount -i image.iso -o “-V cdrfs -o ro” -m /mnt
- To unmount:
- Unmount the file system
# umount /mnt
- Destroy the logical volume
- Unmount the file system
