out of HDD space - zfs degraded
Overnight I was running a zfs send | zfs receive (both within the same system / zpool). The system ran out of space, a drive went off line, and the system is degraded. This is a raidz2 array running on FreeBSD 8.1-STABLE #0: Sat Sep 18 23:43:48 EDT 2010. The following logs are also available at http://www.langille.org/tmp/zfs-space.txt <- no line wrapping This is what was running: #

Reinstalling boot blocks on a ZFS-only system
So, I've long known and it makes sense that when you're booted from a ZFS volume, you can't mess with the boot-loader. And, I know a few months ago I had a set of commands I would use when booted from a CD that would initialize the network and copy the "release/boot" from somewhere else so that I could install bootblocks and boot-loaders from more recent code. Sadly, I

multiple disk failure
Hi, I am using FreeBSD 8.2 and went to add 4 new disks today to expand my offsite storage. All was working fine for about 20min and then the new drive cage started to fail. Silly me for assuming new hardware would be fine :( The new drive cage started to fail, it hung the server and the box rebooted. After it rebooted, the entire pool is gone and in the state below. I had only written a few

Spectacularly disappointing disk throughput
Greetings! I''ve got a FreeBSD-based (FreeNAS) appliance running as an HVM DomU. Dom0 is Debian Squeeze on an AMD990 chipset system with IOMMU enabled. The DomU sees six physical drives: one of them is a USB stick that I''ve passed through in its entirety as a block device. The other five are SATA drives attached to a controller that I''ve handed to the DomU with PCI

10.0-BETA4 (upgraded from 9.2-RELEASE) zpool upgrade -> boot failure
Hi, Is there anything known about ZFS under 10.0-BETA4 when FreeBSD was upgraded from 9.2-RELEASE? I have two servers, with very different hardware (on is with soft raid and the other have not) and after a zpool upgrade, no way to get the server booting. Do I miss something when upgrading? I cannot get the error message for the moment. I reinstalled the raid server under Linux and the other

make_dev_physpath_alias
Hello all. I have a supermicro 16 bay box with a LSI 9211-8i card. We use it for temp data storage, and we wanted to try the l4z compression. After updating the source tree to r247839: and doing a make buildworld cycle all works fine. But at boot time we get some warnings. make_dev_physpath_alias: WARNING - Unable to alias gptid/281951f4-a996-11e1-83eb-00259061b51a to enc at

shutdown -r / shutdown -h / reboot all hang and don't cleanly dismount
Hello -STABLE@, So I've seen this situation seemingly randomly on a number of both physical 9.1 boxes as well as VMs for I would say 6-9 months at least. I finally have a physical box here that reproduces it consistently that I can reboot easily (ie; not a production/client server). No matter what I do: reboot shutdown -p shutdown -r This specific server will stop at "All buffers

Geom label lost after expanding partition
I have a GPT formatted disk where I recently expanded the size of a partition. I used "gpart resize -i 6 ada1" first to expand the partition to use the remaining free space and then growfs to modify the FFS file system to use the full partition. This was all done in single-user mode, of course, but when I enter "exit" to bring the system up, it failed to mount /usr. This was

stable/9: Force ada1 to UDMA-33
Hello, I've got a (P)ATA disk in a special frame. The disk itself supports UDMA-100 (and has an 80-ribbon cable), but the frame isn't compatible with that. By default, FreeBSD negotiates UDMA-100, and the console starts to fill with ICRC errors. In the past, I used a patch to ata-all.c that enabled the following entry in loader.conf to force the disk to UDMA-33, so it worked fine:

Unable to pass device to IOMMU
Hello, I''m hoping someone may be able to push us in the right direction. I''m trying to get one of our products to work with the current branch of Xen (4.0/4.0.0) but I''m hitting a problem. We are currently using Xen 3.3.2 on a Sun Blade 600 chassis (with x6270 blades) this works great. But when we upgrade to Xen 4.0/4.0.1 we get the following message when

FreeBSD 10 Beta 2: make installkernel failure with installer provided ZFS configuration.
Hi, I was trying to rebuild world on a FreeBSD 10 test system, that I had just installed. ZFS root was setup. I let the installation program do all the ZFS setup and configuration. I put root on a 5 disk encrypted raidz array. Besides the installer configuring 5 times the amount of swap space I asked for (asked for 8gb, installer put 8gb on each drive, for 40gb in total.) everything was working

ahcich reset -> cannot mount zfs root in 9.1-PRE
Hi all, Trying to upgrade a system from 9.0-RELEASE to 9.1-PRE from yesterday on my machine (GEOM+ZFS mirror setup on ada[01]p3), the new kernel becomes unable to mount root... The only way to recover is to boot from 9.0 kernel. The disks were already named ada[01] in 9.0, so I suspect nothing there... I tried - disabling AHCI in bios (no change seen) - change cables, check PSU, test disks

[UART] GPS 18-5Hz LVC and COM1 silence, OK on Linux though...
Hi, I'm having issues connecting Garmin GPS 18 to COM1 on 9.1, I get nothing but silence. Identical setup works absolutely fine with Linux. I've got PPS wire connected to DCD, but that seems to make no difference on Linux, so I presume it shouldn't affect fbsd either. On Linux, I get: $ uname -a Linux ubuntu 3.8.0-19-generic #29-Ubuntu SMP Wed Apr 17 18:16:28 UTC 2013 x86_64 x86_64

FreeBSD 9.0 - GPT boot problems?
Hi, I just installed FreeBSD 9.0-release / amd64 on a new machine (Acer Aspire X1470). I installed from a usb memory stick (the default amd64 image), which I booted by pressing "F12" and selecting it from the boot menu on the machine. I installed on a SSD (which replaced the hard drive originally in the machine), using the default scheme for 9.0 (GPT). The installation was painless (many

packet loss on ixgbe using vlans and ipv6
Hi, I have a Dell T710 with 4 X 10G ethernet interfaces (2 X Dual port Intel 82599 cards). It is running FreeBSD RELENG_8 last updated on July 13. What I see is packet loss (0 - 40%) on IPv6 packets in vlans, when the machine is not the originator of the packets. Let me try to describe a little more. If a neigbouring machine ping6 it, there will be packet loss. If it act as a router for ipv6,

RAID10
Hi All, I am looking at ZFS and I get that they call it RAIDZ which is similar to RAID 5, but what about RAID 10? Isn''t a RAID 10 setup better for data protection? So if I have 8 x 1.5tb drives, wouldn''t I: - mirror drive 1 and 5 - mirror drive 2 and 6 - mirror drive 3 and 7 - mirror drive 4 and 8 Then stripe 1,2,3,4 Then stripe 5,6,7,8 How does one do this with ZFS?
