system hangs during dump + compress > usb2-drive
In FreeBSD 8.3 release (possibly in earlier release), dump a file system has 2-3GB or more content can cause system hang in a specific case (pipe to compression): dump FS-on-SATA-drive > usb-drive OK dump FS-on-SATA-drive | anyCompress > sata-drive OK mv a-large-dump-file from STAT drive to a USB drive OK dump small-FS-on-SATA-drive | anyCompress > usb-drive OK small -- 1.8GB or less dump large-FS-on-SATA-drive | anyCompress > usb-drive hang content is 3GB or larger (did not try around 2GB yet) When system hangs, no sub system, such video, network, etc, will function. Typically, the unfinished compressed dump file is around 1.5-2.7GB, so guessing dumped file content is close to or over 2GB when failure occurred. Has anyone encountered the same problem? Because this usually takes a few hours to occur, this is hard to watch how/when it happens. Is any way to debug or determine what status the system is? -Jin ___ 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"

Is any way to debug or determine what > status the system is? For starters I'd use a different console for doing procstat -kk -a and see what the system is doing. (Perhaps also top) I *think* that if it's just hanging for some time, it's probably because the system is trying to take a snapshot? It takes time on UFS when creating and removing the snapshot. Just a guess...

Looking for testers / feedback for ZFS recieve properties options
We encountered a problem receiving a full ZFS stream from a disk we had backed up. The problem was the receive was aborting due to quota being exceeded so I did some digging around and found that Oracle ZFS now has -x and -o options as documented here:- http://docs.oracle.com/cd/E23824_01/html/821-1462/zfs-1m.html Seems this has been raised as a feature request upstream: https://www.illumos.org/issues/2745 Anyway being stuck with a backup we couldn't restore I had a play a implementing these options and have a prototype up and running, which I'd like feedback on. This patch also adds a -l option which allows the streams to be limited to those specified. Another option which I think would be useful and seemed relatively painless to add. The initial version of the patch which is based off 8.3-RELEASE can be found here: http://blog.multiplay.co.uk/dropzone/freebsd/zfs-recv-properties.patch Any feedback appreciated Regards Steve This e.mail is private and confidential between Multiplay (UK) Ltd. and the person or entity to whom it is addressed.
