Author: delphij Date: Fri Jul 18 20:41:40 2014 New Revision: 268855 URL: http://svnweb.freebsd.org/changeset/base/268855Log: MFV r268848: Instead of asserting all zio's be properly aligned, only assert on the logical ones. Cap uberblocks at 8k, otherwise with ashift=17, there would be only one uberblock. This fixes a problem that zdb would trip assert on pools with ashift >= 0xe (8k). While there, also change the code so it only attempt to condense space map unless the uncondensed size consumes greater than zfs_metaslab_condense_block_threshold blocks. Illumos issue: 4958 zdb trips assert on pools with ashift >= 0xe MFC after: 2 weeks
This specific commit makes boot hang just before mounting the root dataset for me when vfs.zfs.vdev.cache.size tunable is set. Unsetting this tunable or reverting this commit (currently running r268933 minus r268855) fixes the boot for me.
Please let me know if I can provide any more information. - Nikolai Lifanov _______________________________________________ svn-src-head@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
