Re: [zfs-discuss] zfs directory symlink owner
"One will be relative (../a/foo) and the other absolute (/mirror/audio-Cd-Tracks/a/foo)." Makes sense. I hadn't actually noticed this. It is not only sharing to Linux machines but also using SFTP as well from outside, so I need things to be pretty much multi-functional and flexible. I don't have any Microsoft machines any more. I survive by creating a pre-defined set of users and groups about 100 above the standard UIDs that all machines have. This gets around needing LDAP for a small home system. Oh, there is the old, modded original X-Box downstairs and that plays the media on those shares as well, so NFS isn't ideal for me.

Re: [zfs-discuss] zfs directory symlink owner
The long ls command worked, as in it created the links, but they didn't work properly under the ZFS SMB share. They didn't work as in, on a remote Linux box, I could execute ls and see them, but I couldn't change in; permission issues. (despite having the correct ownership) and also on the remote linux box, the GUI file browser couldn't even see the folders. By changing in to the directory and then executing the ls command relative to that point, everything worked.

Re: [zfs-discuss] zfs directory symlink owner
Well, This is the overall issue. I have a music collection. The top level folders contain a letter for each artist and each letter then contains a separate folder for each artist. Nice and easy to organise and navigate. A - ACDC - Alanis Morisett B - BeeGees However ... I wanted to create a folder that contains the contents of all 26 folders ... a list of all the artists. Entirelist - ACDC - Alanis Morisett - Bee Gees What I've been doing is creating links in the entirelist folder, which contain links to the sub-folders in each of the letters. very quick, very simple. However, despite having access to all the folders and files, they don't show up in the ZFS SMB share. This means I've got to resort to using cp -L -R /music/A/* /music/entirelist cp -L -R /music/B/* /music/entirelist ...etc. and this takes a long time and probably hammers the hard disk harder than necessary.

Re: [zfs-discuss] Home ZFS NAS - 2 drives or 3?
Perhaps an expert could kindly chime in an opinion of making the drives one large zpool (rather than separate hard partitions) and using the various options within ZFS to ensure that there is always disk space available to the operating system (zpool reservation) ... but the more I sit and think, the more I'm not sure how that would work on the rpool. There are so many ways of handling this. I still think I'd go with hard partitioning for the OS and data, but that is only because of my lack of overall experience with ZFS. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] Home ZFS NAS - 2 drives or 3?
Hi whitetr6, An interesting situation to which there is no, "right," answer. In fact, many different answers depending on where you put your priorities. I'm with Frank in keeping data and OS separate. As you've only got two drives, I'd put between 30 to 40 gig as an OS pool on each drive (making each individually bootable - I was helped out with the method on this thread - http://opensolaris.org/jive/thread.jspa?messageID=454491) and then the remainder of the drives as data. So you've sort of got... Drive 1 - <-30gig OS-> <-720gig data-> Drive 2 - <-30gig OS-> <-720gig data-> ...completely mirrored and independently bootable. Open Solaris creates its boot partition as a Zpool anyway, so it is relatively straightforward to mirror it. I made a short video of the advice that I was given, here - http://www.youtube.com/watch?v=tpzsSptzmyA - and that technique will also cover you for installing on drives of different sizes, so if you upgrade the hard drives later, this technique will hold solid and also enable you to add another drive should you have to replace one. You might have to adjust that advice if you're not using your entire drive for the system partition. The only thing I've ever seen take out both internal drives at the same time is a power surge by either external sources, or an overheated PSU blowing in the PC. Surge protection and adequate cooling should minimise the risks. I'm assuming you've got a routine to take snapshots and get them off the box; based on what you've already written. Having an OS booting from USB is possible; from what I've seen of ZFS so far, I believe it would be possible to attach two USB keys and have them mirrored and bootable also! But personally I don't see any real need to do it this way. So, if I were in your shoes, I'd partition as per above and run the two hard disks ... but have an external drive available for backup. It would be worth practising the technique of mirroring the root partition, handling zpools and recovering from failures before committing data to it. The practice is well worth it IMHO. I hope this helps. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] zfs rpool mirror on non-equal drives
I did notice the findroot command, but I don't know what I'm doing when it comes to Grub. The video is up http://www.youtube.com/watch?v=tpzsSptzmyA - just me droning on for ten minutes and it is aimed at people following me, so I do a lot of explaining the basics. I have to agree with a previous poster in that I'd rather use fdisk and partition, than the fmthard command.

Re: [zfs-discuss] zfs rpool mirror on non-equal drives
Another question ... I did this as a test because I am aware that zpools don't like drives switching controlers without being exported first. The question was, what would a rpool boot drive do if it was put on a different controller and then booted? I shut down, took away c7 and hooked c19 up to the SATA cable that I used to connect c7 to ... just out of interest to see what would happen. I was half expecting it to have a problem booting, and half expecting it to come up as c7 ... but it still came up as c19 in the zpool status.

[zfs-discuss] zfs rpool mirror on non-equal drives
Hi Folks, As usual, trust me to come up with the unusual. I'm planning ahead for future expansion and running tests. Unfortunately until 2010-2 comes out I'm stuck with 111b (no way to upgrade to anything than 130, which gives me problems) Anyway, here is the situation. Initial installation drive is a 40gig drive given over to Open Solaris. Second drive is an 80 gig drive. The aim is to mirror the operating system in a way that I can remove the 40gig drive form the system and have the 80 gig drive boot. At this point, you're probably thinking that you've heard it all before. I believe that the drive size difference is causing a problem. I kill the EFI partition and set up a Solaris partition. Yes, I even reboot the box to ensure that the Solaris partition has stuck. I run the usual ... prtvtoc /dev/rdsk/c4t0d0s2 | fmthard -s – /dev/rdsk/c4t1d0s2 ... command and it is here that I think something is going wrong ... ... because when I add the drive to the zpool, it flips the partition back to EFI, which means my grub installation is useless. Some extra information is that I can't add c19d0s0 - I have to add c19d0. This could be one point where it is reverting it to EFI. If I try to add c19d0s0 I get, "cannot open '/dev/dsk/c19d0s0': No such device or address" ... which makes me think that the fmthard is putting wrong information on to the 80gig drive because the "slice" sizes will be different. Have I reached the right conclusion? If so, how do I get around this? Do I have to somehow manually slice the drive up? -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
