I've figured it out. It turned out that the iscsi disk was offline. I managed to turn if online from within Windows but how would turn it online/offline from with Linux ?

Do you know what module isgetting loaded? It might be due to the other block dev error above. If you are trying to read the module from a iscsi disk, then the problem is probably that there was a bug in the scsi layer above and you cannot access the disk due to it, so you get the error below. If the module was on some local disk, then I am not sure. > I get the following call traces: > > [ 3699.105931] INFO: task modprobe:1342 blocked for more than 120 > seconds. > [ 3699.105945] "echo 0> /proc/sys/kernel/hung_task_timeout_secs" > disables this message. > [ 3699.105949] modprobe D ffff8800815bd000 0 1342 1 > [ 3699.105955] ffff880006881838 0000000000000286 ffff880007ded818 > ffff880006143800 > [ 3699.105961] ffff8800014eca40 ffff8800014bf640 ffff8800014eccc0 > 000000008020e810 > [ 3699.105967] 0000000000000000 ffff8800067e2368 00000000000024b2 > ffff8800815bd000 > [ 3699.105972] Call Trace: > [ 3699.105986] [<ffffffff8020e911>] xen_clocksource_read+0xd/0x9c > [ 3699.105992] [<ffffffff80264711>] sync_page+0x0/0x41 > [ 3699.105996] [<ffffffff80243f1e>] getnstimeofday+0x39/0x98 > [ 3699.106001] [<ffffffff80264711>] sync_page+0x0/0x41 > [ 3699.106006] [<ffffffff802b12eb>] blkdev_readpage+0x0/0xf > [ 3699.106011] [<ffffffff80434297>] io_schedule+0x5c/0x9e > [ 3699.106016] [<ffffffff8026474d>] sync_page+0x3c/0x41 > [ 3699.106020] [<ffffffff8043440a>] __wait_on_bit_lock+0x36/0x66 > [ 3699.106028] [<ffffffff802646fe>] __lock_page+0x5e/0x64 > [ 3699.106034] [<ffffffff8023f6b7>] wake_bit_function+0x0/0x23 > [ 3699.106038] [<ffffffff80264cf3>] read_cache_page_async+0xc3/0x121 > [ 3699.106044] [<ffffffff80266464>] read_cache_page+0x6/0x3b > [ 3699.106049] [<ffffffff802cfd57>] read_dev_sector+0x2a/0x88 > [ 3699.106056] [<ffffffff802d0520>] adfspart_check_ICS+0x0/0x164 > [ 3699.106060] [<ffffffff802d0547>] adfspart_check_ICS+0x27/0x164 > [ 3699.106065] [<ffffffff802d0520>] adfspart_check_ICS+0x0/0x164 > [ 3699.106070] [<ffffffff802d040c>] rescan_partitions+0x123/0x237 > [ 3699.106075] [<ffffffff802b0f7b>] do_open+0x234/0x2e8 > [ 3699.106079] [<ffffffff802d522c>] sysfs_ilookup_test+0x0/0xf > [ 3699.106084] [<ffffffff802b109f>] __blkdev_get+0x70/0x82 > [ 3699.106097] [<ffffffff802d0293>] register_disk+0xe7/0x13d > [ 3699.106103] [<ffffffff80305963>] add_disk+0x3a/0x87 > [ 3699.106110] [<ffffffffa01401e5>] :sd_mod:sd_probe+0x317/0x3d8 > [ 3699.106117] [<ffffffff80378cac>] driver_probe_device+0xd0/0x14d > [ 3699.106121] [<ffffffff80378d6f>] __driver_attach+0x46/0x6d > [ 3699.106125] [<ffffffff80378d29>] __driver_attach+0x0/0x6d > [ 3699.106129] [<ffffffff80378480>] bus_for_each_dev+0x44/0x6f > [ 3699.106134] [<ffffffff8037889e>] bus_add_driver+0xae/0x1e4 > [ 3699.106139] [<ffffffff80378ff6>] driver_register+0x84/0xe7 > [ 3699.106144] [<ffffffffa014608b>] :sd_mod:init_sd+0x8b/0xee > [ 3699.106150] [<ffffffff8024c5a2>] sys_init_module+0x191b/0x1ab1 > [ 3699.106170] [<ffffffffa00aab89>] :scsi_mod:scsi_set_medium_removal > +0x0/0x70 > [ 3699.106179] [<ffffffff8020b528>] system_call+0x68/0x6d > [ 3699.106183] [<ffffffff8020b4c0>] system_call+0x0/0x6d > [ 3699.106187] > > Also with fdisk I get: > > DebianTemp:~# fdisk /dev/sda > > Unable to open /dev/sda > DebianTemp:~# > > > Would anybody be able to tell me what's happening? > -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
