Hi, We have recently experienced what appear to be XFS filesystem errors on a samba share. The actual filesystem resides on a network attached storage device, a Coraid. The attached server locked up totally, and we forced to hard reset it. I have the following trace from the kernel logs: [6128798.051868] smbd: page allocation failure. order:4, mode:0xc0d0 [6128798.051872] Pid: 16908, comm: smbd Not tainted 2.6.32-5-amd64 #1 [6128798.051874] Call Trace: [6128798.051882] [<ffffffff810ba5d6>] ? __alloc_pages_nodemask+0x592/0x5f4 [6128798.051885] [<ffffffff810b959c>] ? __get_free_pages+0x9/0x46 [6128798.051889] [<ffffffff810e7ea1>] ? __kmalloc+0x3f/0x141 [6128798.051893] [<ffffffff8110672c>] ? getxattr+0x89/0x117 [6128798.051896] [<ffffffff810e5b65>] ? virt_to_head_page+0x9/0x2a [6128798.051899] [<ffffffff810f9bc4>] ? user_path_at+0x52/0x79 [6128798.051919] [<ffffffffa0297b17>] ? xfs_xattr_put_listent+0x0/0xe5 [xfs] [6128798.051922] [<ffffffff810e5b65>] ? virt_to_head_page+0x9/0x2a [6128798.051925] [<ffffffff8118ddcb>] ? _atomic_dec_and_lock+0x33/0x50 [6128798.051928] [<ffffffff811068b4>] ? sys_getxattr+0x45/0x60 [6128798.051931] [<ffffffff81010b42>] ? system_call_fastpath+0x16/0x1b smbd seems to throw these errors for about 15 minutes, then sshd starts throwing errors and shortly after the system became unresponsive. Just wondering if anyone had any experience of similar results, with XFS on a CoRAID device or XFS SMB shares? Thanks Jon -- Jon Marshall Technical Officer jon@xxxxxxxxxxxxxxxxxx .
