erm..... using a file on another pool (your zpool) for the SLOG is NOT a good idea. Use an SSD or two (a mirror) or let ZFS deal with the ZIL on the drives.
roy Hello All, I've recently run into an issue I can't seem to resolve. I have been running a zpool populated with two RAID-Z1 VDEVs and a file on the (separate) OS drive for the ZIL: raidz1-0 ONLINE c12t0d0 ONLINE c12t1d0 ONLINE c12t2d0 ONLINE c12t3d0 ONLINE raidz1-2 ONLINE c12t4d0 ONLINE c12t5d0 ONLINE c13t0d0 ONLINE c13t1d0 ONLINE logs /ZIL-Log.img This was running on Nexenta Community Edition v3. Everything was going smoothly until today when the OS hard drive crashed and I was not able to boot from it any longer. I had migrated this setup from an OpenSolaris install some months back and I still had the old drive intact. I put it in the system, booted it up and tried to import the zpool. Unfortunately, I have not been successful. Previously when migrating from OSOL to Nexenta I was able to get the new system to recognize and import the ZIL device file. Since it has been lost in the drive crash I have not been able to duplicate that success. Here is the output from a 'zpool import' command: pool: tank id: 9013303135438223804 state: UNAVAIL status: The pool was last accessed by another system. action: The pool cannot be imported due to damaged devices or data. see: http://www.sun.com/msg/ZFS-8000-EY config: tank UNAVAIL missing device raidz1-0 ONLINE c12t0d0 ONLINE c12t1d0 ONLINE c12t5d0 ONLINE c12t3d0 ONLINE raidz1-2 ONLINE c12t4d0 ONLINE c12t2d0 ONLINE c13t0d0 ONLINE c13t1d0 ONLINE I created a new file for the ZIL (using mkfile) and tried to specify it for inclusion with -d but it doesn't get recognized. Probably because it was never part of the original zpool. I also symlinked the new ZIL file into /dev/dsk but that didn't make any difference either. Any suggestions?
