8.0RC1, ZFS: deadlock
Hello, I have observed a deadlock condition when using ZFS. We are making a heavy usage of zfs send/zfs receive to keep a replica of a dataset on a remote machine. It can be done at one minute intervals. Maybe we're doing a somehow atypical usage of ZFS, but, well, seems to be a great solution to keep filesystem replicas once this is sorted out. How to reproduce: Set up two systems. A dataset with heavy I/O activity is replicated from the first to the second one. I've used a dataset containing /usr/ obj while I did a make buildworld. Replicate the dataset from the first machine to the second one using an incremental send zfs send -i pool/data...@nminus1 pool/data...@n | ssh destination zfs receive -d pool When there is read activity on the second system, reading the replicated system, I mean, having read access while zfs receive is updating it, there can be a deadlock. We have discovered this doing a test on a hopefully soon in production server, with 8 GB RAM. A Bacula backup agent was running and ZFS deadlocked. I have set up a couple of VMWare Fussion virtual machines in order to test this, and it has deadlocked as well. The virtual machines have little memory, 512 MB, but I don't believe this is the actual problem. There is no complaint about lack of memory.

I did so by checking out stable/8 under /usr/src, rebuilding kernel/world, and using portupgrade to update all installed ports from packages available on the 8.0RC1 DVD-iso. Since the update, my X11 is laggy. Now, I often have to move the mouse before keystrokes/button presses take effect. Make sure hal and dbus are enabled in rc.conf and running. In xorg.conf, remove Option AllowEmptyInput off. A bonus of using hal is that you can remove the keyboard and mouse sections from xorg.conf. As I've mentioned, I've updated the kernel/world, and updated libpciaccess. Perhaps I'm having issues because I need to remove old libs. How do I remove old libs? cd /usr/src make check-old-libs make delete-old-libs I deleted old libs using 'make delete-old-libs' from /usr/src, but that has led to many other problems. It seems many libraries currently in use were deleted in the process. I'm having to rebuild/reinstall many of my applications to get them working again. I'm seeing something similar to OP, apparent keyboard buffer delays, but maybe not exactly. When I click from one xterm to another, it may be 1 - 30 seconds before my key entries show. Firefox seems to have less delay after clicks into text fields, but sometimes it is noticeable maybe 0.25 to 1 second. Just two xterms, the fluxbox toolbar, and firefox running. No frufru stuff. I haven't had time to systematically try to narrow down the actual problem. Wiggling the mouse, hitting various keys all seemed like they helped at one time or another, but I think I was just trying things until the buffer released. If I leave it alone, the delays seem to be of about the same length as when I'm trying random things to break it loose. Only clicking in a window (particularly an xterm) seems to stall the keyboard buffer. Just wiggling the mouse above or around the focused window is no problem. Clicks take effect immediately. I can drag the window by the title bar or resize the window without stalling the keyboard buffer. I haven't lost a key press that I've noticed. Now I just type blind until it catches up or I actually need to see the results of my typing. Oh, it seems like if there is something in the xterm which can use the mouse input, it may not be stalling the keyboard buffer. I need to watch that more closely. I've tried with and without an explicit xorg.conf. Switching back to the console works better without. With doesn't leave me a usable display outside of X. It seems like the delays get longer and longer the longer the X session has been up. But sometimes there will be no delay. If I switch windows/desktops with alt-tab, ctrl-f#, there is no delay. I've been wondering if it could be due to the synaptics touchpad. I enabled the synaptics features about the same time to try to get rid of tap events from the touchpad. I hate touchpads and still haven't figured out how to kill tapping. agp0: Intel GM965 SVGA controller on vgapci0 I've done the delete-old stuff and got mad at KDE4 and did a pkg_delete -a in a fit of rage. I went back with fluxbox, took about 2 to 3 hours to compile everything from source to have my multiple xterms back. Firefox took another 2 hours. But I was able to *work* while that built. I was running FreeBSD 8-CURRENT pre-beta cycle. KDE4 was giving me so many fits that I would just run Windows instead so I could get work done, sad. I don't know if I would have noticed an input buffer delay before I upgraded to BETA2 and replaced KDE with fluxbox. I just couldn't stand to spend that much time in X. Windows finally annoyed me enough to try something different (fluxbox). This problem has been with me through the BETAs and now into RC1, as far as I can remember. I've been busy and trying really hard to ignore workstation issues to get work done ever since my PowerBook died. When upgrading from one major release of FreeBSD to another, the standard recommendation is to delete all installed applications (pkg_delete -a) and then reinstall everything. There may be some incantation of portupgrade or portmaster that will do it. pkg_libchk from sysutils/bsdadminscripts may help. But that is likely to take longer than just pkg_delete -a and reinstalling applications. portmaster's man page suggests pkg_delete -a. It has explicit instructions so you don't miss anything putting them back on. Not that I've used the instructions yet. Rage is not condusive to reading manuals. I did a 'pkg_delete -a' to delete all packages, and then installed fresh packages from the
Booting FreeBSD 8.0-RC1 from usb stick
Hi all, FreeBSD 8.0-RC1 was installed onto hard disk. The root filesystem was transferred to a usb memory stick via #pwd / # find -print . -x | cpio -pdm /mnt/usbstick The fstab on the stick was modified such that / was to be mounted from /dev/da0s1a, the ufs fs on the usb stick. This had proven to work perfectly with 7.2. In 8.0-RC1, however, this approach fails. After booting the kernel, the system does not automatically mount the / partition. Instead, it asks for a partition to mount to /, and when exactly the same location is entered (ufs:/dev/da0s1a), it mounts this partition and works perfectly. Explicitly setting the root partition (vfs.root.mountfrom=ufs:/dev/da0s1a) in /boot/loader.conf does not help either: Again, the system knows which partition it should mount to /, but it fails to do so. (vfs.root.mountfrom.options=rw was set too). Any ideas?

Do you see the USB stick probe and appear after the kernel has tried to mount it, like in that PR, or do you see the USB stick probe before mountroot is attempted, but it still fails? Either way, you could try the attached hack. Be aware that this really is not the correct fix, but might at least be enough to get you going until the correct fix is in place.

I think a lot of people would define need differently than you do. Part of being on a public mailing list is dealing with traffic in formats that you don't necessarily like or would choose to use. The robustness principle fits here, Be liberal in what you accept, and conservative in what you send. I know I probably don't have your pgp public key and a lot more users probably do not either. There are ways to address that problem. I see that you're using Alpine, not sure what you're using for PGP in association with that. My own mail/pine-pgp-filters port works quite well for this purpose. You can also include the following in your gpg.conf: keyserver-options auto-key-retrieve which will retrieve the keys for you without intervention. (FWIW, I also recommend the options no-include-revoked, import-clean, and export-clean.) Personally I keep the keys that I care about in their own keyring files, and allow the random keys to be imported into pubring.gpg. That way I can nuke that ring, or keys on it any time and know I'm not losing anything important. I'll leave that configuration as an exercise for the reader. :) If I do not have your public key in my keyring then I do not want it, do not need it and have no use for it at this time. This keeps my keyring small and manageable. Well yay for you! :) However explaining your reasoning isn't making you sound any more reasonable.

In other words, it should not be relied upon to work either. Please revert whatever patch John gave you and try the attached patch. It simply disables the use of 1GB page mapping by the direct map. Your patch fixes (works around?) the problem. Thanks. I've committed the patch. Yes, it's a work around. Fortunately(?), on my test machine, I don't see any measurable effect from disabling the use of 1GB pages by the direct map. Btw I had reported the same issue back in June already, http://lists.freebsd.org/pipermail/freebsd-current/2009-June/008709.html and yes your patch fixes it for me too. Thanx!

Re: PATA disks/DVD not detected on ATI IXP 700 - cannot boot (dmesg attached)
On Monday 28 September 2009 02:21 pm, Alexander Motin wrote: Here we can see detected: 4 (not 6!) SATA channels on AHCI controller, one PATA channel and 2 SATA channels in legacy emulation (why?). Actually, the same happens if I comment out all that device class magic. Looks like the only thing really required to fix problem with two lost channels is this part of patch: -/* IXP600 IXP700 only have 1 PATA channel */ -if ((ctlr-chip-chipid == ATA_ATI_IXP600) || - (ctlr-chip-chipid == ATA_ATI_IXP700)) +/* IXP600 only have 1 PATA channel */ +if (ctlr-chip-chipid == ATA_ATI_IXP600) Looks like part of changing device class just not working. Today I have bought IXP700 based board and can acknowledge that the same situation I can see with recent HEAD. `pciconf -l` reports to me original PATA device class and only 4 channels reported by AHCI. So jkim@, could you please comment, how should it really work and why it doesn't? My patch fixed two things: a) combined mode and b) the above fix. The combined mode is very unusual. When combined mode is turned on from BIOS, two SATA ports appear as legacy ATA device. Depending on the configurations, device ID changes. :-( To enable this feature, some BIOSes allow flexible (and yet confusing) combinations like this: http://people.freebsd.org/~jkim/sb700-ata.png Also, almost all SB700 BIOSes out there have broken ACPI DSDT which do not set these bits properly. Thus, some ports disappear if we don't force setting the subclass and progif. Note it should be *partially* worked around by the latest ACPICA on -CURRENT, though. PS: I have tried to disable all that ATI-specific code and found that both legacy PCI ATA and AHCI drivers looks like working fine with IXP700. Do we really need AHCI forcing for IXP700? It enables all six SATA ports as SATA and one PATA channel as PATA in the combined mode by forcing the mode. It is not absolutely necessary but it is better than without it, IMHO. :-) Jung-uk Kim ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org
