Re: Disk_config lens for Augeas
Hi, [...] This mail is to inform you that a new lens for FAI disk_config files was added to Augeas. It can currently be found in the git repository of the Augeas project [1]. This lens will turn disk_config files into a tree that can be parsed with xpath using Augeas. [...] Thanks a lot for this nice work! [...] Bug reports, suggestions, patches are all welcome. I'd have two suggestions, yes: - You should probably use http://wiki.fai-project.org/wiki/Setup-storage as a more permanent URL. - Yet I'm afraid the information on the wiki is partly outdated. The most up-to-date information is in the man page of setup-storage. If you find the time to check consistency of the grammars that would be awesome.

If you find the time to check consistency of the grammars that would be awesome. I have noticed that the schema on the wiki is outdated, and sometimes not functional even. With the lens in the current state, I've been able to successfully parse 477 disk_config files we use in production. I'd be happy to get more tricky cases to test if you wish to send some to me.

Hi again, [...] I have noticed that the schema on the wiki is outdated, and sometimes not functional even. With the lens in the current state, I've been able to successfully parse 477 disk_config files we use in production. I'd be happy to get more tricky cases to test if you wish to send some to me. I think the following three examples should be of such nature: Config 1: disk_config disk1 bootable:1 preserve_always:all always_format:5,6,7,8,9,10,11 primary - 0 - - primary - 0 - - logical / 0 ext3 rw,relatime,errors=remount-ro createopts=-c -j logical swap 0 swap sw logical /var 0 ext3 rw,relatime createopts=-m 5 -j logical /tmp 0 ext3 rw createopts=-m 0 -j logical /usr 0 ext3 rw,relatime createopts=-j logical /home 0 ext3 rw,relatime,nosuid,nodevcreateopts=-m 1 -j logical /wrk 0 ext3 rw,relatime,nosuid,nodevcreateopts=-m 1 -j logical /transfer 0 vfat rw Config 2: disk_config /dev/sda primary - 250M - - primary - 20G - - logical - 8G- - logical - 4G- - logical - 5G- - disk_config /dev/sdb sameas:/dev/sda disk_config raid raid1 /boot sda1,sdb1 ext3 defaults raid1 / sda2,sdb2 ext3 defaults,errors=remount-ro raid1 swap sda5,sdb5 swap defaults raid1 /tmp sda6,sdb6 ext3 defaults createopts=-m 1 raid1 /var sda7,sdb7 ext3 defaults Config 3: disk_config /dev/sdb primary / 21750 ext3 defaults,errors=remount-ro primary /boot 250ext3 defaults logical - 4000 - - logical - 2000 - - logical - 10-- - disk_config cryptsetup randinit swap swap /dev/sdb5 swap defaults tmp /tmp /dev/sdb6 ext2 defaults luks /local00 /dev/sdb7 ext3 defaults,errors=remount-ro createopts=-m 0 Thanks again for your work, Michael pgpVUs3UR1q4z.pgp Description: PGP signature
Re: shorten dmesg.log
Hi, Would you mind taking a look at the logtail patch that's been sitting in experimental for almost forever already? I don't see how this can possibly work on something like the kernel message buffer. Its contents will rotate once it runs full so the offset noted by logtail will no longer be correct. I think the only way of handling that is putting a marker into the buffer that will also rotate. (In case it rotates out, we take everything we can get, which is just what would be done now.) Please note that my patch relies on /var/log/kern.log instead of dmesg, hence no ring buffer here. But I might be missing something else. Best, Michael pgp7LMkupIVMl.pgp Description: PGP signature
