Hi, Found the root cause, the 3.5.1 kernel cannot mount my ext4 filesystem (60TB). The 3.4 kernel works fine. This is proven by commenting out the filesystem in /etc/fstab with 3.5.1, and all is OK. -- Hi again, I tested with linux-3.6-rc1: The same problem, here is what I get from the strace: irectory) 4434 readlink("/dev", 0x7fff3b05c670, 4096) = -1 EINVAL (Invalid argument) 4434 readlink("/dev/sda1", 0x7fff3b05c670, 4096) = -1 EINVAL (Invalid argument) 4434 readlink("/r1", 0x7fff3b05c670, 4096) = -1 EINVAL (Invalid argument) 4434 getuid() = 0 4434 geteuid() = 0 4434 getgid() = 0 4434 getegid() = 0 4434 prctl(PR_GET_DUMPABLE) = 1 4434 lstat("/etc/mtab", {st_mode=S_IFLNK|0777, st_size=12, ...}) = 0 4434 getuid() = 0 4434 geteuid() = 0 4434 getgid() = 0 4434 getegid() = 0 4434 prctl(PR_GET_DUMPABLE) = 1 4434 stat("/run", {st_mode=S_IFDIR|0755, st_size=820, ...}) = 0 4434 lstat("/run/mount/utab", {st_mode=S_IFREG|0644, st_size=0, ...}) = 0 4434 open("/run/mount/utab", O_RDWR|O_CREAT, 0644) = 3 4434 close(3) = 0 4434 mount("/dev/sda1", "/r1", "ext4", MS_MGC_VAL|MS_NOATIME, NULL -- (w/ 3.6-rc1) [ 89.868843] mount R running task 0 4434 4433 0x00000009 [ 89.868847] ffff880c246b7b68 ffffffff816c9279 ffff880c246b7aa8 ffff880c246b7fd8 [ 89.868851] ffff880c246b7fd8 0000000000004000 ffff88062720cdb0 ffff880c246862d0 [ 89.868855] 00000000000116c0 ffff880623a863c0 ffff880623a863c0 00000000ffffffff [ 89.868855] Call Trace: [ 89.868858] [] ? __schedule+0x299/0x770 [ 89.868860] [] ? __schedule+0x299/0x770 [ 89.868864] [] ? ext4_get_group_desc+0x49/0xb0 [ 89.868868] [] ? ext4_calculate_overhead+0x131/0x3e0 [ 89.868871] [] ? ext4_fill_super+0x1a4b/0x28d0 [ 89.868875] [] ? mount_bdev+0x1a1/0x1e0 [ 89.868877] [] ? ext4_calculate_overhead+0x3e0/0x3e0 [ 89.868880] [] ? ext4_mount+0x10/0x20 [ 89.868882] [] ? mount_fs+0x1b/0xd0 [ 89.868885] [] ? vfs_kern_mount+0x6f/0x110 [ 89.868888] [] ? do_kern_mount+0x4f/0x100 [ 89.868890] [] ? do_mount+0x2fe/0x8a0 [ 89.868894] [] ? strndup_user+0x53/0x70 [ 89.868896] [] ? sys_mount+0x90/0xe0 [ 89.868899] [] ? tracesys+0xd4/0xd9 Justin.
