LVM miscalculates bitmap size with small extent, so start with 16K as
for other RAID types.
Until version 2.02.103 LVM counts metadata segments twice when checking
available space, reduce segment count by one to account for this bug.
Write activity with LVM/RAID can happen after filesystem is unmounted.
In my testing modification time of loop files was 15 - 20 seconds
after unmount. So use time as close to unmount as possible as
reference instead.
Tests file access with all filters enabled. It does it both for local
and network access, due to regression in signature checking over network.
This includes all files in distribution to not depend on existence
of compression tools and gpg. Test preloads all required modules to
avoid having to provide signatures for them.
Still not implemented is file offset filter (is not available in grub
script, needs extra module)
Basic usage would look something like this:
gptprio.next -d usr_dev -u usr_uuid
linuxefi ($usr_dev)/boot/vmlinuz mount.usr=PARTUUID=$usr_uuid
After booting the system should set the 'successful' bit on the
partition that was used.
In order to do anything with partition GUIDs they need to be stored in a
proper structure like the partition type GUIDs. Additionally add an
initializer macro to simplify defining both GUID types.
The first hint of something practical, a command that can restore any of
the GPT structures from the alternate location. New test case must run
under QEMU because the loopback device used by the other unit tests does
not support writing.
The header location fields refer to 'this header' and 'alternate header'
respectively, not 'primary header' and 'backup header'. The previous
field names are backwards for the backup header.
This module is a new implementation for reading GUID Partition Tables
which is much stricter than the existing part_gpt module and exports GPT
data directly instead of the generic grub_partition structure. It will
be the basis for modules that need to read/write/update GPT data.
The current code does nothing more than read and verify the table.
Copying the themes directory in grub-shell isn't
parallel-test-friendly and breaks on the second test when the source
directory is read-only (as in "make distcheck"). Instead, add a
hidden --themes-directory option to grub-mkrescue et al, and use it
in grub-shell.
the function of these files exceeds what can be sanely handled in shell
in posix-comaptible way. Also writing it in C extends the functionality
to non-UNIX-like OS and minimal environments.
