Re: [zfs-discuss] zfs cksum calculation
Hi, Thanks for the prompt response. I tried using digest with sha256 to calculate the uberblock checksum. Now, digest gives me a 65 char's ouput, while zdb -uuu pool-name, gives me only 49 char output. how can this be accounted? I'm trying to understand how the checksum is calculated and displayed in zdb -uuu. Please help.

I just added -xarch=amd64 in Makefile.master and then could compile the driver without any issues. Regards, pak. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] changing guid of vdev
Hi, I added a vdev(file) to the zpool and then, and using hexedit modified the guid of the vdev in all four labels. I also, caluculated the new ub_guid_sum and updated all uberblock guid_sum values. Now, when I try to import this modified file into the zpool, it says the device is offline...and debugging the driver got to know that in spa_load: ub-ub_txg == 0 so, ENXIO. Is this a checksum related issue? can I not do what I was trying to do? if I should not, can someone please let me know how to change the guid?

I would like to know why its picking up amd64 config params from the Makefile,
while uname -a clearly shows that its i386 ?
