Re: After the FreeBSD VM crash, file system in VM got rolled back to some old previous state causing data loss

This happened with FreeBSD guest with UFS (journaled soft-updates) and FreeBSD host. What is out of normal, it rolled back for many hours (~20). Yuri Could be you are using *Immutable images *as type of disk for guest VM 1. *Immutable images.* When an image is switched to immutable mode, a differencing image is created as well. As with snapshots, the parent image then becomes read-only, and the differencing image receives all the write operations. Every time the virtual machine is started, all the immutable images which are attached to it have their respective differencing image thrown away, effectively resetting the virtual machine's virtual disk with every restart. http://www.virtualbox.org/manual/ch05.html //BR, Sergey ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org
Discussing ideas or wish list
Hello, FreeBSD is so powerful and great. I would like to discuss some ideas or wish list with you guys: 1) Perl version change within Major release If I remembered correctly, FreeBSD 9.0 shipped with perl 5.12 packages in the DVD. But in FreeBSD 9.1, Perl 5.14 is shipped. I think Perl version should be consistent in the FreeBSD 9 series. The change of Perl version may make user difficult to upgrade other perl packages due to dependency issues. I know pkgng should replaced the old package management tools in FreeBSD 10, I hope the situation would improve. 2) pkgng I think it has checksum checking on the files in the packages. Could pkgng detect the packages was being tampered? Or how can user authenticate that the package is build by FreeBSD? 3) FreeBSD's own systat Yes. there is bsdsar in the ports, but I would like to see improvement. For example, stat for multiple CPU, number of open files/context switches, one statistics file per day, etc...

For the information you want do: a) Type on terminal/xterm #systat 1 b) Press ':' and type 'vmstat' (without quotes) You have the statistics updated every second. Press ':' and type 'help' to see other commands information screens.

The change of Perl version may make user difficult to upgrade other perl packages due to dependency issues. The ports tree is a rolling release and decides what the default perl version is, not the FreeBSD release. Let's ignore that though and take a peek into history using FreeBSD 8 series as an example because it's closer to EoL. Perl 5.8.0 is officially released July 18, 2002. Perl 5.8.9 is officially EoL on Nov 6, 2008. FreeBSD 8.0 released Nov 25, 2009. The ports tree's default Perl version at that point in time is Perl 5.8.9. Both Perl 5.8.9 and 5.10.1 are available as packages at that time. FreeBSD 8.4 released June 7, 2013. The ports tree's default Perl version at that point in time is 5.14.2. FreeBSD 8.4 could be the last release in the FreeBSD 8.x series. Its estimated EoL is June 30, 2015. Do you see the problem with having to support an ancient Perl version that is 13 years old? I'd suspect many modern Perl applications to not even work on Perl 5.8.9. I know pkgng should replaced the old package management tools in FreeBSD 10, I hope the situation would improve. After the EoL of FreeBSD 8 (estimated June 30, 2015) the old package tools are scheduled to be removed from FreeBSD. This change will be MFC'd back to 9-STABLE and the release at that time (perhaps 9.4-RELEASE?) will not have the old pkg_* tools. This seems a bit odd to happen in the middle of a series because of POLA, but we can't support the old package tools forever and FreeBSD 9.1-9.3 will have given you plenty of opportunity to migrate to the new package format and ease the upgrade to FreeBSD 10.x. 2) pkgng I think it has checksum checking on the files in the packages. Could pkgng detect the packages was being tampered? man pkg-check pkg check -s is used to find invalid checksums for installed packages. Or how can user authenticate that the package is build by FreeBSD? I don't think packages are signed yet, but this is permitted by the new pkg design and will hopefully happen before too long. 3) FreeBSD's own systat Yes. there is bsdsar in the ports, but I would like to see improvement. For example, stat for multiple CPU, number of open files/context switches, one statistics file per day, etc... I think systat is great, too. We could probably import some functionality from OpenBSD as I recall their systat has more features. Thank you for your feedback and I hope I've answered a couple of your questions. ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to freebsd-hackers-unsubscr...@freebsd.org

It depends. FreeBSD's systat has some features that OpenBSD's doesn't have and vice versa (list take from the manpages): FreeBSD: icmpDisplay, in the lower window, statistics about messages icmp6 This display is like the icmp display, but displays statis- ip Otherwise identical to the icmp display, except that it dis- ip6 Like the ip display, except that it displays IPv6 statistics. tcp Like icmp, but with TCP statistics. OpenBSD: buckets Display kernel malloc(9) bucket statistics similar to the malloc Display kernel malloc(9) type statistics similar to the nfsclient Display statistics about NFS client activity. Output nfsserver Display statistics about NFS server activity. Output pf Display filter information about pf(4), similar to the output poolDisplay kernel pool(9) statistics similar to the output of queues Display statistics about the active altq(9) queues, similar rules Display pf rules statistics, similar to the output of pfctl sensors Display the current values of available hardware sensors, in states Display pf states statistics, similar to the output of pfctl pgpJtZh7gV2iW.pgp Description: PGP signature

The OS release schedule got reworked after the RoadMap was written and the security incident and the consequent necessity of completely redesigning and rebuilding the pkgng package building system has added various delays too.
