TAPEFS(1) General Commands Manual TAPEFS(1) NAME
32vfs, cpiofs, tapfs, tarfs, tpfs, v6fs, v10fs - mount archival file systems SYNOPSIS
fs/32vfs [ -m mountpoint ] [ -p passwd ] [ -g group ] file fs/cpiofs fs/tapfs fs/tarfs fs/tpfs fs/v6fs fs/v10fs DESCRIPTION
These commands interpret data from traditional tape or file system formats stored in file, and mount their contents (read-only) into a Plan 9 file system. The optional -p and -g flags specify Unix-format password (respectively group) files that give the mapping between the numeric user- and group-ID numbers on the media and the strings reported by Plan 9 status inquiries. The -m flag introduces the name at which the new file system should be attached; the default is /n/tapefs. 32vfs interprets raw disk images of 32V systems, which are ca. 1978 research Unix systems for the VAX, and also pre-FFS Berkeley VAX sys- tems (1KB block size). Cpiofs interprets cpio tape images (constructed with cpio's c flag). Tarfs interprets tar tape images. Tpfs interprets tp tapes from the Fifth through Seventh Edition research Unix systems. Tapfs interprets tap tapes from the pre-Fifth Edition era. V6fs interprets disk images from the Fifth and Sixth edition research Unix systems (512B block size). V10fs interprets disk images from the Tenth Edition research Unix systems (4KB block size). SOURCE
These commands are constructed in a highly stereotyped way using the files fs.c and util.c in /sys/src/cmd/tapefs, which in turn derive substantially from ramfs(4). SEE ALSO

TGTIMG(8) TGTIMG(8) NAME
tgtimg - Linux SCSI Target Framework Image File Utility SYNOPSIS
tgtimg [-o --op <operation>] [-Y --device-type <device-type>] [-b --barcode <barcode>] [-s --size <size>] [-t --type <media-type>] [-f --file <path>] tgtimg --help DESCRIPTION
Tgtimg is a utility to create and manage the image files used by the TGTD device emulation. This command is used to initialize device image files with the additional metadata, such as barcode, list of blocks, total size, etc that the TGTD emulation needs. OPTIONS
-h, --help Show a help screen and exit. -o, --op {new|show} Operation. Is either new to create a new image file or show to show the content of an existing image file. -Y, --device-type <type> This specifies the type of image file. Supported device types are : cd : to create media for a dvd device disk : to create media for a disk device tape : to create media for a tape device -t, --type <media-type> When creating a new image, this specifies the type of media to emulate. The available mediatypes depend on the type of the device. Supported media types for cd devices are : dvd+r : create a blank writeable DVD+R disk Supported media types for disk devices are : disk : create an empty disk Supported media types for tape devices are : data : create a normal data tape clean : create a cleaning tape worm : create a worm -b, --barcode <barcode> When creating a new image, this argument specifies the barcode to use with this image file. Backup application software often uses barcodes to identify specific tapes. When emulating a VTL, make sure that all tape images use unique barcodes. -s, --size <size> When creating a new image, this specifies the size in megabytes for the virtual tape image. -f, --file <path> The filename of the image file. EXAMPLES
To create a new 100MByte disk tgtimg --op new --device-type disk --type disk --size 100 --file /data/hd001.raw To create a new tape image tgtimg --op new --device-type tape --barcode 12345 --size 100 --type data --file /data/tape001.img To view the content of an existing image tgtimg --op show --device-type tape --file /data/tape001.img To create a new blank DVD+R image tgtimg --op new --device-type cd --type dvd+r --file /data/dvd001.iso SEE ALSO
