Bug 22217

Reassigning to QA Team

nilfs-utils-2.2.7-1.mga6

Assignee: bugsquad => qa-bugs

MGA6-32 on Dell Latitude D600 MATE
No installation issues
I have no such filesystem, but could do:
$ lscp -h
Usage: lscp [OPTION]... [DEVICE]
  -a, --all		show all checkpoints
  -b, --show-block-count		show block count
  -g, --show-increment		show increment count
  -r, --reverse		reverse order
  -s, --snapshot	list only snapshots
  -i, --index		cp/ss index
  -n, --lines		lines
  -h, --help		display this help and exit
  -V, --version		display version and exit
$ lscp -V
lscp (nilfs-utils 2.2.7)
$ lssu /dev/sda1
lssu: cannot open NILFS on /dev/sda1: No such file or directory

Seems all correct behavior.

We are unlikely to be able to test this in present circumstances: unless we find a real user, it would entail creating & using a nilfs2 filesystem. This page gives a handy "Using NILFS" resumé with explicit commands:
 https://nilfs.sourceforge.io/en/about_nilfs.html
May yet try it.

Testing M6/64

There is a host of associated programs, all with man pages:
 /sbin/mkfs.nilfs2
 /sbin/mount.nilfs2
 /sbin/nilfs_cleanerd
 /sbin/umount.nilfs2
 /usr/bin/chcp
 /usr/bin/dumpseg
 /usr/bin/lscp
 /usr/bin/lssu
 /usr/bin/mkcp
 /usr/bin/rmcp
 /usr/sbin/nilfs-clean
 /usr/sbin/nilfs-resize
 /usr/sbin/nilfs-tune
 lscp     lists checkpoints.
 mkcp     makes a checkpoint.
 mkcp -s  makes a snapshot.
 chcp     changes an existing checkpoint to a snapshot or vice versa.
 rmcp     invalidates specified checkpoint(s).

Copied a big mixed directory to /mnt/tmp/ . Viewed various files, edited a few, confirmed that the changes 'stuck'. Did a big unzip. Deleted some files.

No O/P to any of these.

Did not persue checkpoint|snapshot generation, mounting, conversion, deletion.
Looks functional. OKing & validating. Advisory done.
