did this get fixed in the latest update kernel? using 2.6.9-1.681_FC3smp with the xfs qa test suite I see a few other errors, but not this one anymore, so looks like this bug can go away. Closing with NOTABUG (anymore) because the drop down list doesn't give me any other options. :) |
Description of problem: mount occasionally hangs saw this while running through xfsqa; certainly does not happen every time but i've seen it about 3-4 times in the course of running a 90-test qa suite 4-5 times. Anyway - Mounting an xfs filesystem: 30181 pts/0 R 1:16 /bin/mount -t xfs -ologbsize=256k /dev/sda2 /mnt/sda2 never returns. I shoehorned kdb into fc2; it doesnt' seem very happy but here's what I get out of it: [0]kdb> btp 30181 Stack traceback for pid 30181 0x039a9930 30181 29982 1 1 R 0x039a9bc0 mount ESP EIP Function (args) 0x05aa3f3c 0x02153fa7 rw_vm+0x18f (0x0, 0x1000, 0x4bd1000) kernel 0x2153e18 0x2154103 0x05aa3f74 0x02154443 get_user_size+0x2e (0x5aa3fa8, 0x5aa3fc4, 0xc0ed0000) kernel 0x2154415 0x215446a 0x05aa3f88 0x02172d76 copy_mount_options+0x4d kernel 0x2172d29 0x2172dc0 0x05aa3fa0 0x0217326c sys_mount+0x13 kernel 0x2173259 0x21733b9 [0]kdb> md 0x4bd1000 0x04bd1000 00736678 00000000 00000000 00000021 .sfx...........! 0x04bd1010 62676f6c 657a6973 3635323d 6f6c2c6b bgolezis652=ol,k 0x04bd1020 69736267 323d657a 006b3635 00000021 isbg2=ez.k65...! 0x04bd1030 62676f6c 657a6973 3635323d 6f6c006b bgolezis652=ol.k 0x04bd1040 69736267 323d657a 006b3635 00000021 isbg2=ez.k65...! 0x04bd1050 62676f6c 657a6973 3635323d 6f6c2c6b bgolezis652=ol,k 0x04bd1060 69736267 323d657a 006b3635 00020039 isbg2=ez.k65...9 0x04bd1070 00000000 00000000 00000000 00000000 ................ so although this is an xfs mount it's not in xfs code that things are stuck... any suggestions for further debugging this w/o kdb would be appreciated; sysrq-t doesnt' give me any useful info since the process is running and no stack is generated.
