NetBSD ZFS port TODO
|
|
|
|
1) ZVOL part
|
|
|
|
* zpool cannot be destroyed -> could not destroy 'test': could not unmount datasets
|
|
We are leaking descriptor after open -> I'm getting EBUSY from spscfs_open.
|
|
|
|
2) ZPL part
|
|
|
|
* test zfs_vfsops.c and zfs_vnops.c changes
|
|
* xattr and acl support is needed for filesystem permisions ?
|
|
* Check if we are calling vfs_option clear set routines from vfs.c with mnt_updating lock held.
|
|
* Port zfs_replay.c -> DONE
|
|
|
|
3) ZFS part
|
|
|
|
* ACL support, xattr calls support
|
|
* Snapshots support
|
|
* iSCSI targets support
|
|
* NFSv3, NFSv4 support
|
|
* Samba filesystem support
|
|
* Implement getpages/putpages for zfs, can be done with genfs_* routines but vnode_t need some changes.
|
|
* zfs_rename support, Working but there are some issues with LOCKDEBUG see comment above zfs_rename.
