Message-ID: <20081003170452.50a7ec78@harpe.intellique.com> Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Sender: xfs-bounce@oss.sgi.com Errors-to: xfs-bounce@oss.sgi.com List-Id: xfs To: xfs@oss.sgi.com After a system crash on a system with a 40TB XFS filesystem, xfs_repair (32 bits binary, with a 64 bits 2.6.24 kernel) refused to work ("cannot allocate block map, size xxx"). The 64 bits xfs_repair did the trick fine. I tried to reproduce the problem today by corrupting a 22TB filesystem. However, 32 bits xfs_repair repaired the 22 TB FS just fine in the very same configuration (64 bits kernel, etc). I thought the limit would be at 16TB (32 bits limit for a filesystem) but obviously this isn't the case. Is the limitation higher (like 32 TB) or is it a bug of etch 4.0r4 xfs_repair? -- ---------------------------------------- Emmanuel Florac | Intellique ----------------------------------------
