* MFOpenZFS: Add basic zfs ioc input nvpair validationToomas Soome2020-06-234-13/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We want newer versions of libzfs_core to run against an existing zfs kernel module (i.e. a deferred reboot or module reload after an update). Programmatically document, via a zfs_ioc_key_t, the valid arguments for the ioc commands that rely on nvpair input arguments (i.e. non legacy commands from libzfs_core). Automatically verify the expected pairs before dispatching a command. This initial phase focuses on the non-legacy ioctls. A follow-on change can address the legacy ioctl input from the zfs_cmd_t. The zfs_ioc_key_t for zfs_keys_channel_program looks like: static const zfs_ioc_key_t zfs_keys_channel_program[] = { {"program", DATA_TYPE_STRING, 0}, {"arg", DATA_TYPE_UNKNOWN, 0}, {"sync", DATA_TYPE_BOOLEAN_VALUE, ZK_OPTIONAL}, {"instrlimit", DATA_TYPE_UINT64, ZK_OPTIONAL}, {"memlimit", DATA_TYPE_UINT64, ZK_OPTIONAL}, }; Introduce four input errors to identify specific input failures (in addition to generic argument value errors like EINVAL, ERANGE, EBADF, and E2BIG). ZFS_ERR_IOC_CMD_UNAVAIL the ioctl number is not supported by kernel ZFS_ERR_IOC_ARG_UNAVAIL an input argument is not supported by kernel ZFS_ERR_IOC_ARG_REQUIRED a required input argument is missing ZFS_ERR_IOC_ARG_BADTYPE an input argument has an invalid type Reviewed by: allanjude Obtained from: OpenZFS Sponsored by: Netflix, Klara Inc.

* zfs: Add option for forcible unmounting dataset while receiving snapshot.Mariusz Zaborski2020-04-114-11/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently when the dataset is in use we can't receive snapshots. zfs send test/1@asd | zfs recv -FM test/2 cannot unmount '/test/2': Device busy This commits add option 'M' which attempts to forcibly unmount the dataset. Thanks to this we can enforce receiving snapshots in a single step. Note that this functionality is not supported on Linux because the VFS will prevent active mounted filesystems from being unmounted, even with the force option. This is the intended VFS behavior.

* MFOpenZFS: make zil max block size tunableAlexander Motin2020-03-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've observed that on some highly fragmented pools, most metaslab allocations are small (~2-8KB), but there are some large, 128K allocations. The large allocations are for ZIL blocks. If there is a lot of fragmentation, the large allocations can be hard to satisfy. The most common impact of this is that we need to check (and thus load) lots of metaslabs from the ZIL allocation code path, causing sync writes to wait for metaslabs to load, which can take a second or more. In the worst case, we may not be able to satisfy the allocation, in which case the ZIL will resort to txg_wait_synced() to ensure the change is on disk. To provide a workaround for this, this change adds a tunable that can reduce the size of ZIL blocks.

* Speed up "zpool import" in the presence of many zvolsAlan Somers2020-01-281-0/+12
| | | | | | | | | | | | | | | | | | | By default, zpools may not be backed by zvols (that can be changed with the "vfs.zfs.vol.recursive" sysctl). When that sysctl is set to 0, the kernel does not attempt to read zvols when looking for vdevs. But the zpool command still does. This change brings the zpool command into line with the kernel's behavior. It speeds "zpool import" when an already imported pool has many zvols, or a zvol with many snapshots.

* libzfs: add zfs_mount_atKyle Evans2020-01-192-5/+27
| | | | | | | | | | | | | | | | | | | | | | This will be used in libbe in place of the internal zmount(); libbe only wants to be able to mount a dataset at an arbitrary mountpoint without altering dataset/pool properties. The natural way to do this in a portable way is by creating a zfs_mount_at() interface that's effectively zfs_mount() + a mountpoint parameter. zfs_mount() is now a light wrapper around the new method. The interface and implementation have already been accepted into ZFS On Linux, and the next commit to switch libbe() over to this new interface will solve the last compatibility issue with ZoL. The next sysutils/openzfs rebase against ZoL should be able to build libbe/bectl with only minor adjustments to build glue.

| | | | | | | | | | | | | | | | | | | | | | | The DOF file output by dtrace -A contains only the loadable sections. However, as it was created by a call to dtrace_dof_create() without flags, the original DOF was created with the loadable sections. The result is that the DOF includes the section headers for the unloadable sections (COMMENTS and UTSNAME) without these sections actually being present. This is inconsistent. A simple change to anon_prog() ensures that the missing sections are present in the outputted DOF. Alternatively, the call to dtrace_dof_create() could pass the DTRACE_D_STRIP flag stripping out the loadable sections. As the unloadable sections contain info useful for debugging purposes they haven't been stripped.

* MFZoL: Avoid retrieving unused snapshot propsAlan Somers2019-10-266-32/+111
| | | | | | | | | | | | | | | | | | | | | This patch modifies the zfs_ioc_snapshot_list_next() ioctl to enable it to take input parameters that alter the way looping through the list of snapshots is performed. The idea here is to restrict functions that throw away some of the snapshots returned by the ioctl to a range of snapshots that these functions actually use. This improves efficiency and execution speed for some rollback and send operations.
