They're running a 2.6.9-rc2-mm1 kernel and are Dell PowerEdge 1750 dual Xeon servers with 4G ECC Reg. and 3 disks in sw-raid 5. The systems still responds to ping and listens to ie. the mysql port, but does not give a MySQL prompt, seems the disks are in deadlock state or so ? Using the sysrq showTasks I see the following traces (I will only show some since the total log is much too long to show here, the full log including the .config can be found on http://roel.net/backtrace/): pdflush D 00000008 0 56 15 57 23 (L-TLB) f7ca7c10 00000046 f7ca7c00 00000008 00000003 00000000 00000000 6c4e4dc0 00000011 c31c6000 00000000 00000000 f64ff800 00000000 00000000 00000000 00000000 00000008 00000000 006d3803 00000013 c2fca020 00000003 c31c6154 Call Trace: [] __down+0x8e/0x10d [] default_wake_function+0x0/0x12 [] __down_failed+0x8/0xc [] .text.lock.md+0x9b/0xf3 [] make_request+0x1df/0x226 [] generic_make_request+0x113/0x194 [] mempool_alloc+0x8b/0x15d [] autoremove_wake_function+0x0/0x57 [] submit_bio+0x70/0x121 [] bio_alloc+0xd9/0x1ac [] submit_bh+0xe0/0x133 [] reiserfs_write_full_page+0x2eb/0x4d0 [] reiserfs_writepage+0x26/0x3e [] mpage_writepages+0x207/0x3b2 [] reiserfs_writepage+0x0/0x3e [] d_rehash+0x55/0x79 [] simple_lookup+0x40/0x44 [] do_writepages+0x3d/0x43 [] __sync_single_inode+0x66/0x1f1 [] __writeback_single_inode+0x70/0x157 [] generic_sync_sb_inodes+0x1dd/0x2e7 [] pdflush+0x0/0x2c [] sync_inodes_sb+0xba/0xc9 [] get_super_to_sync+0x54/0x75 [] sync_inodes+0x2b/0x90 [] do_sync+0x23/0x74 [] __pdflush+0xbf/0x191 [] pdflush+0x28/0x2c [] do_sync+0x0/0x74 [] pdflush+0x0/0x2c [] kthread+0xb7/0xbd [] kthread+0x0/0xbd [] kernel_thread_helper+0x5/0xb sshd D 00000008 0 24085 1220 24084 (NOTLB) e8e59cac 00000082 e8e59c98 00000008 00000003 00000001 e9e60b7c bd0483c0 00000004 e8e19000 e8e29900 e8e28440 e8e1b080 00000082 c04830c0 f3ff6550 00000000 e9e60b7c e8e1b080 dcda1904 00000012 c2fca020 00000003 e8e19154 Call Trace: [] __down+0x8e/0x10d [] default_wake_function+0x0/0x12 [] __down_failed+0x8/0xc [] .text.lock.journal+0x4b/0xcb [] journal_begin+0x6b/0xc3 [] reiserfs_dirty_inode+0x58/0xd3 [] __mark_inode_dirty+0x1d2/0x1d7 [] update_atime+0xd9/0xde [] do_generic_mapping_read+0x3cb/0x53d [] __generic_file_aio_read+0x1ef/0x22b [] file_read_actor+0x0/0xec [] link_path_walk+0x9ed/0xd38 [] generic_file_read+0xba/0xd2 [] __vma_link+0x44/0x73 [] do_mmap_pgoff+0x509/0x779 [] autoremove_wake_function+0x0/0x57 [] sys_fstat64+0x37/0x39 [] vfs_read+0xbc/0x127 [] sys_read+0x51/0x80 [] syscall_call+0x7/0xb etc. not sure which are relevant here, so please look at the mentioned location above.
