(my quick and ditry hack to install a system with LVM) Here some excerpts from my newest generic installation script Install Date: (not installed) Build Host: lamb10 Name : rear Relocations: (not relocatable) This was on SLES12SP1, with rear 2.00 package from OBS: After I hit 'y' on console, restore process continues. This prompt is visible in the log file, but not on system's console, there is just an empty line with a blinking cursor. Wipefs: Use the -force option to force erase. Wipefs: /dev/sda1: ignoring nested "dos" partition table on non-whole disk device +++ echo -e 'Creating filesystem of type ext3 with mount point /boot on /dev/sda1.' +++ Print 'Creating filesystem of type ext3 with mount point /boot on /dev/sda1.' 14:36:14 Creating filesystem of type ext3 with mount point /boot on /dev/sda1.
p, -parsable Print out in parsable instead of printable format.During a restore, depending on what condition the target disk is in, wipefs will sometimes not wipe existing filesystem from the block device, and subsequent mkfs will stall the whole process, by interactively asking for confirmation: It is possible to specify multiple -o options. The offset number may include a "0x" prefix, and then the number o, -offset offset Specifies location (in bytes) of the signature which should be erased from the device. n, -no-act Causes everything to be done except for the write() call. Options -a, -all Erase all available signatures. Without options -a or -o, it lists all visible filesystems and offsets of their signatures. wipefs does not erase the whole filesystem or any other data from the device. Wipefs allows to erase filesystem or raid signatures (magic strings) from theĭevice to make the filesystem invisible for libblkid.
