If there are already separate partitions inside the slice, I'd agree there is no compelling reason to move to a multiple slice system. An idea would be, for example, to remove the /usr partition and create two new partitions, one for /usr and one for /usr/local, which would move out /usr/local contents from the partition holding /usr - which I think is what the OP originally intended.

Produce identical packages for checksum comparison?
I have a somewhat flaky system. I would like to compile ports to packages multiple times and do a file comparison. Since packages are tar files they wouldn't match for sure just because of the different time attributes. There may be other differences.

Hi Chris, What is behind the idea to compile and pack a given port twice if there are no errors during the build? matthias While I don't think there will be differences I won't know until I do it. Call it reassurance. To me it seems like a good stress test. Also every time I update my ports tree I don't know what is going to break. I have a jail running all the time to recompile my ports as they are updated. I maintain between three to five different different ports/packages branches of different checkout dates. The system is somewhat flaky and crashes sometimes. I play with a lot of stuff and am actually using Freebsd as my desktop. I am sure that most of my crashing is due to multiple jails and using nullfs and unionfs but that isn't relevent to my current post. I'm also thinking of building a simple checksum database to track what actually changes and what my options were when I compiled it. It would allow me to better make regression decisions. I could also be free to delete packages and know if I recompile it later that it was the exact same package with the exact same options. Very simple script to do that. Also if say there was an option when compiling ports to produce files with specific time/dates it would be helpful in pinpointing which of my port branches a specific file came from.

Is there a way to take the drive offline then use atacontrol to spin it down or something so it is easy to identify? In my opinion you are best off using glabel(8) to give names to the disks. This way you can name them in a way that makes sense to you. Additionally, when you create the ZFS pool you will use the glabel'd names. This means that the pool will still come up properly if something causes your devices to be numbered differently (i.e. a drive dies and you happen to reboot the system). I believe ZFS does this automatically. Supposedly, if you take a working set of RAIDZ drives from one machine and put it in another, ZFS will figure out the drives since they get labelled by ZFS internally. My question concerns how to identify the physical disk in question based on the adX or glabel name? Different name in software is fine, but if the drive fails I want to make sure I pull the correct drive. This is possible, but I don't remember reading that ZFS handles this anywhere, and I've seen glabel(8) recommended elsewhere for the same reason. Either way, you can add your drives one-by-one and label them on the enclosure arraydrive00 and then glabel the individual disks with the same name. This way when ZFS tells you arraydrive03 is dead/offline, you can look at your enclosure and pull the drive with the arraydrive03 label. Depending on your controller it is also probably worth it to use one of the SATA-specific drivers in FreeBSD 8 - these are ones like ahci(4) and siis(4). While the generic ata(4) driver will work for pretty much everything, the updated AHCI drivers can take advantage of some more features. Enable the modules at boot to use them. I will look into it, thanks. The machine in question is 2 year old hardware currently with a 3ware raid card. I will be going software raid only, but FreeBSD already recognizes the eSATA drive I have attached as a backup device so I know the O/S can at least talk to sata drives attached to the mobo. ___ 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 One thing to note about resilvering; unlike most raid systems zfs knows what is going on at the filesystem level as well as block level. Therefore when a drive has to be resilvered, only the data on the drive is rebuilt rather than every block as with most other raid subsystems. eg if you have a 1TB hd but only have 20 Gig of data, only 20 gig is copied/rebuilt rather than 1 TB of data if you were using gvinum/gmirror. This massively speeds up rebuild times and stress on the other drives.

The elusive reproducible build. Many people are interested in doing this, and it's not as easy as it seems. Even if you edited your filesystem or archives to change the timestamps of package files, the toolchain used to create the binary files in packages often injects random seeds, timestamps, file paths, uid/gid information, etc. that creates differences from one build to the next. You may have to hack several base system utilities, and then directly compare the checksums of binaries in archives after unpacking, or use a more intelligent comparison.

[FreeBSD Questions] Filesystem image as root
I have been thinking and experimenting for weeks, but I cannot figure this out. I have an Intel SS4200 NAS that I wish to use as a ZFS NAS with FreeBSD 8.0. The device has 4 SATA bays, and I don't want to use one for a UFS root disk. I don't want to use up hundreds of megabytes of RAM preloading an mfsroot that can never shrink. The single IDE connector is accessible via the legacy ISA ports, and is thus limited to PIO modes (about 1.6MB/sec max, even with an actual hard drive instead of a CF card). Performance is acceptable when using a geom_uzip image from a CF card on the IDE connector, as a lot of it ends up cached in RAM (and is evictable in case of memory pressure, unlike an mfsroot). Try as I might, I am unable to figure out how to use a uzip imagefile on UFS as a root filesystem, without dedicating a slice/partition to it. There seems to be nothing approximating GNU/Linux's pivot_root, and using a stub init (which cannot be a shellscript...?) to mdconfig and mount the image, then chroot to that to exec /sbin/init appears to lead to instant deadlock. I don't really like the idea of mounting the image somewhere below root, and using symlink spaghetti to get everything proper; especially since I wish to place such essentials as /sbin and /etc thereupon, which leads to a bit of a chicken-and-egg problem with setting up and mounting an image that contains its mdconfig and mount... Am I missing something obvious here, or am I truly treading unexplored territory? -- Fuzzy love, -CyberLeo Technical Administrator CyberLeo.Net Webhosting http://www.CyberLeo.Net cyber...@cyberleo.net Furry Peace! - http://.fur.com/peace/ ___ 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
