Yes, I Am! Hi Pawel, Thanks for you excellent work on ZFS! I want to report that I got again a kmem_map_too_small panic on recent - - -current with the new ZFS version. I left the machine overnight with an endless loop running bonnie++ on a raidz2 zfs pool with five disks, and I found it dead this morning. Is this still supposed to happen? I had only these two lines in my loader.conf : vm.kmem_size="1536M" vm.kmem_size_max="1536M" and i have just added vfs.zfs.arc_max="768M" and will run the torture test again. (the default value for arc_max was 1006632960) Btw, the machine is amd64 with four gigabytes of RAM, and I have upgraded the pool to version 13. Thanks! - -- Regards, Nikolay Denev -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (Darwin) iEYEARECAAYFAkkj0E0ACgkQHNAJ/fLbfrnQ2ACdFWNUKgZALVICj/6/2gMPhSzl 6/AAoLqDt8MfIgA+qAZQAhHf65sdGYjS =9y3s -----END PGP SIGNATURE-----
