Re: [zfs-discuss] Mount order of ZFS filesystems vs. other filesystems?
Hello Kyle! All of these mounts are failing at bootup with messages about non-existent mountpoints. My guess is that it's because when /etc/vfstab is running, the ZFS '/export/OSImages' isn't mounted yet? Yes, that is absolutely correct. For details, look at the start method of svc:/system/filesystem/local:default, which lives in the script /lib/svc/method/fs-local. There you can see that ZFS is processed after the vfstab. Any ideas? The only way I could find was to set the mountpoint of the file system to legacy, and add it to /etc/vfstab. Here's an example: # ZFS legacy mounts: SHELOB/var - /var zfs - yes - SHELOB/opt - /opt zfs - yes - SHELOB/home - /home zfs - yes - # # -- loopback mount -- begin # loopback mount for /usr/local: /opt/local - /usr/locallofs - yes ro,nodevices /home/cvs - /opt/local/cvs lofs - yes rw,nodevices # -- loopback mount -- end Before I added /home to vfstab, the loopback for /opt/local/cvs would fail.

The only way I could find was to set the mountpoint of the file system to legacy, and add it to /etc/vfstab. Here's an example: I tried this last night also, after sending the message and I made it work. Seems clunky though. Yes, I also would have liked something more streamlined. But since adding entries to vfstab worked I did not pursue if further. I wonder if there is a technical reason why it has to be done in this order? I can only guess that anything else would have been too complex. The whole sequence seems to have room for improvement. For example in svc:/system/filesystem/root:default there are some checks to mount optimized libc and hwcap libraries, and /usr is mounted, but not the root fs (which I would have expected going by the FMRI name). More importantly, I wonder if ZFS Boot will re-order this since the other FS's will all be ZFS. My guess is that the whole thing will be rewritten. (Actually I wonder what will be left in /etc/vfstab?) Good question. I would think that the file will still be around; it'll have all the non-ZFS mount points, but the root fs will be mounted by ZFS. # ZFS legacy mounts: SHELOB/var - /var zfs - yes - SHELOB/opt - /opt zfs - yes - SHELOB/home - /home zfs - yes - # # -- loopback mount -- begin # loopback mount for /usr/local: /opt/local - /usr/locallofs - yes ro,nodevices /home/cvs - /opt/local/cvs lofs - yes rw,nodevices # -- loopback mount -- end Before I added /home to vfstab, the loopback for /opt/local/cvs would fail.

[zfs-discuss] Mount order of ZFS filesystems vs. other filesystems?
I seem to be having a problem mounting the filesystems on my machine, and I suspect it's due to the order of processing of /etc/vfstab vs. ZFS mount properties. I have a UFS /export, then I have a ZFS that mounts on /export/OSImages. In that ZFS I have a couple of directories with many .ISO files. In /etc/vfstab, I have entries that mount the ISO's using LOFI onto mountpoints which are also located under /export/OSImages. All of these mounts are failing at bootup with messages about non-existent mountpoints. My guess is that it's because when /etc/vfstab is running, the ZFS '/export/OSImages' isn't mounted yet? Any ideas? After bootup, I can login and run 'mountall' manually and everything mounts just fine. -Kyle ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
