From fe7caa7c4a3bb738d3eb3ac6edaa24c8b38ec95f Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Wed, 15 Dec 2010 16:02:45 -0500 Subject: [PATCH] Check for RAID10 in set_avail_alloc_bits When raid is setup with mkfs, it is supposed to cow the initial filesystem it creates up to the desired raid level. RAID10 was not in the list of RAID levels it checked for, so the initial FS created for RAID10 actually only lived on the first disk. This works well enough because all the roots get quickly cowed during the first mount. The exception is the data relocation tree, which only gets cowed when we do a balance.
