Re: setup journaling for root partition
thanks, i do as you said, but after loading gjournal, dd says operation not permitted. gjournal clear says operation not permitted too and therefore gjournal label is not done and say previous error (gjournal cannot clear metadata on ad3s1a: operation not permitted). and -v return no extra log. i don't know why i can not do any thing in fixit mode:( is this a true procedure? i mean maybe i should do any thing else because freebsd handbook set journaling for user partition in single user mode not in fixit mode. i test it and it works well, but for root partition i can not do the same because root partition can not be unmount in single user mode. any hints or comments are really appreciated. thanks in advance On Thu, May 23, 2013 at 10:41 AM, Michael Sierchio ku...@tenebras.comwrote: On Wed, May 22, 2013 at 10:53 PM, s m sam.gh1...@gmail.com wrote: thanks Michael for your quick reply:) yes, i can boot from usb freebsd flash and use fixit mode. i have root, var, tmp, usr and swap on my system. i create an extra swap partition to use it as journal provider for root partition. in fixit mode, first i run two below command in order to abel load gjournal: ln -s /dist/lib /lib ls -s /dist/boot/kernel /boot/modules then gjournal load and after that: gjournal label -f ad3s1a ad3s1g (ad3s1a is root partition and ad3s1g is swap partition for journal provider) but this error is shown: gjournal cannot clear metadata on ad3s1a: operation not permitted what is wrong here??? i really don't know how to fix it: Try using -v to get more verbose output.

Re: ZFS install on a partition
Le 17/05/2013 ? 20:03:30-0400, Paul Kraus a écrit ZFS is stable, it is NOT as tuned as UFS just due to age. UFS in all of it's various incarnations has been tuned far more than any filesystem has any right to be. I spent many years managing Solaris system and I was truly amazed at how tuned the Solaris version of UFS was. I have been running a number of 9.0 and 9.1 servers in production, all running ZFS for both OS and data, with no FS related issues. Have you ever try to update a ZFS Pool on 9.0 to 9.1 ? I've a server with a big zpool in 9.0 I'm wonder if it's good idea to upgrade to 9.1. If I lost the data I'm close to dead person. If I thinking to upgrade to 9.1 it's because I got small issue about NFSD, LACP. Regards.

Yes, this RAID is good, but unless you use SSD disks to boost performance and a lot of RAM the hardware raid should be more reliable and mush faster. Why will the hardware raid be more reliable ? While hardware raid is susceptible to uncorrectable errors from the physical drives (hardware raid controllers rely on the drives to report bad reads and writes), and the uncorrectable error rate for modern drives is such that with high capacity drives (1TB and over) you are almost certain to run into a couple over the operational life of the drive. 10^-14 for cheap drives and 10^-15 for better drives, very occasionally I see a drive rated for 10^-16. Run the math and see how many TB worth of data you have to write and read (remember these failures are generally read failures with NO indication that a failure occurred, bad data is just returned to the system). In terms of performance HW raid is faster, generally due to the cache RAM built into the HW raid controller. ZFS makes good use of system, Before I'm installing my server under 9.0 + ZFS I do some benchmarks with ionice to compare FreeBSD 9.0+ ZFS + 12 disk SATA 7200 rpm vs CentOS + H700 + 12 disk SAS 15krpm (Both are same Dell poweredge). And the ZFS+12 disk sata goes much faster than CentOS+H700+ext4 almost everywhere. Only for small file AND small record size the ZFS is slower than CentOS. The server don't have SSD.

I've a server with a big zpool in 9.0 I'm wonder if it's good idea to upgrade to 9.1. If I lost the data I'm close to dead person. If I thinking to upgrade to 9.1 it's because I got small issue about NFSD, LACP. My data zpool is not that big, only five 1TB drives in a raidZ2 for a net capacity of about 3TB, plus one 1TB hot spare. My suggestion is to do the following (which is how I did the upgrade): 1) on a different physical system install 9.1, get the OS configured how you want it 2) on the production server, export the data zpool 3) shutdown the production server 4) remove the OS drives from the production server and replace with the drives you just installed 9.1 on 5) booth the production server with the 9.1 OS drives, make sure everything is working the way you want 6) import the data zpool If the import fails, you can always put the 9.0 drives back in and get back up and running fairly quickly.

Strange behavior of NFS/ZFS on 9.0
Hi all, I've a server under FreeBSD 9.0 with a large ZFS pool (~ 150To) This server is use mainly for backup and NFS server, he also have 4 Gb/s interface bound with LACP. If the nfs client is close to the server (physical distance) everything is fine. When the client is far away (NFS over tcp of course) from the client side everything work (it's slow but it's working), the strange thing is when the client do some « heavy » acces to the server through NFS, we cannot ping the server during 10-30 sec and the ping come back, and some time later ( ~10-15 min) again we cannot ping the server. When I quote « heavy » it's because the traffic is ~ 40 Mbit/s. I'm sure of the relation between client acces through NFS and lost ping. Anyone have a idea.

netgraph network for jail(8) vnet jail unable to reach internet
Hello list.
Trying to get my script to work that creates a netgraph network for a
jail(8) vnet jail. Every thing seems to work, but from inside of the
started vnet jail I can not ping the public internet. The host can ping
the public internet so the problem has to be in the netgraph script. The
problem must be staring me in the face but I can just not see it. A
fresh pair of eyes may see things I am missing.
I'm running 9.1-RELEASE with vimage compiled into the kernel. Non-vnet
jails work fine and bridge/epair networked vnet jails work fine. The
host has a single ethernet interface (rl0) facing the public internet.
Dhcp is used to get the hosts ip address and dns server info. The
vnet.ng script is designed to create a single ng bridge to rl0 and
connect vnet jails to it as the jails are started. The following is a
walk through of a test cycle showing what I can see from the host. At
the end is a listing of the vnet.ng script.
Thanks for your help

ZFS guarantees no silent failures, it doesn't guarantee protection, only that you'll know about it. There is no filesystem that can guarantee you won't lose data in a power failure. Hard drives are known to lie about what's been physically synced to disk out of cache in order to improve speed. If the power goes out at the wrong time, you can lose data. ZFS can find a corrupted file and tell you, everything else won't.

That's a judgement call, which means it depends. i heard so much about soft update -that is added in freebsd9.1- which can fix file corruption in acceptable way with low cost but i don't know how much is reliable and efficient. Several things: Soft updates have been around for quite a while. Soft updates journaling is the new addition. Neither of these address file corruption. Their purpose is to make sure the filesystem does not get corrupted, but individual files could still contain bad data. in the other hand, i think migration from UFS to ZFS can be another solution. as i read ZFS is is created to solve all the problems related integrity file system. is it reliable enough in comparison soft-update? now, i want to know which solution is better and why? Again, it depends. Does the target system have enough RAM for ZFS? If the file corruption is due to a hardware problem or an application writing bad data, no filesystem can prevent that. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

A couple thoughts off the top of my head: a. Did you enable promiscuous mode on rl0 via ngctl? (in your script perhaps?) b. Have you tried giving ngeth0 a new MAC address? (I do this through ngctl too, but I imagine ifconfig from within the jail could achieve the same thing) -- Devin Yes I enabled promiscuous mode and setautosrc 0 on rl0 via ngctl. I can find no documentation on why this is done. Can you point me to some? Yes I gave the jail a unique MAC address. I tried to generate my own network map, but having problem. ngctl dot file.dot works. dot -Tsvg -o file.svg file.dot gives me command dot not found. Please install graphics/graphviz, either from ports or from packages. Tried ngctl dot -Tsvg -o file.svg file.dot and -T is illegal option. What am I doing wrong?
