Trying to mount a dataset from a readonly pool could inadvertently start the user accounting upgrade task, leading to the following failure: VERIFY3(tx->tx_threads == 2) failed (0 == 2) PANIC at txg.c:680:txg_wait_synced() Showing stack for process 2541 CPU: 2 PID: 2541 Comm: z_upgrade Tainted: P O 3.16.0-4-amd64 #1 Debian 3.16.51-3 Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 Call Trace: [<0>] ? dump_stack+0x5d/0x78 [<0>] ? spl_panic+0xc9/0x110 [spl] [<0>] ? dnode_next_offset+0x1d4/0x2c0 [zfs] [<0>] ? dmu_object_next+0x77/0x130 [zfs] [<0>] ? dnode_rele_and_unlock+0x4d/0x120 [zfs] [<0>] ? txg_wait_synced+0x91/0x220 [zfs] [<0>] ? dmu_objset_id_quota_upgrade_cb+0x10f/0x140 [zfs] [<0>] ? dmu_objset_upgrade_task_cb+0xe3/0x170 [zfs] [<0>] ? taskq_thread+0x2cc/0x5d0 [spl] [<0>] ? wake_up_state+0x10/0x10 [<0>] ? taskq_thread_should_stop.part.3+0x70/0x70 [spl] [<0>] ? kthread+0xbd/0xe0 [<0>] ? kthread_create_on_node+0x180/0x180 [<0>] ? ret_from_fork+0x58/0x90 [<0>] ? kthread_create_on_node+0x180/0x180 This patch updates both functions responsible for checking if we can perform user accounting to verify the pool is not readonly.
