Xin LI 1b174fa1eb MFV r268455: ... Use reserved space for ZFS administrative commands. We reserve 1/2^spa_slop_shift = 1/32 or 3.125% of pool space (or 32MB at least) for system use. Most ZPL operations, e.g. write(2), creat(2), will fail with ENOSPC if we fall below this. Certain operations, e.g. file removal and most administrative actions, still permitted until half of the slop space is used. This would allow users to use these operations to free up space in the pool when pool is close to full but half of slop space is still free. A very restricted set of operations that frees up space or change quota are always permitted, regardless of the amount of free space. MFC after: 2 weeks		2014-07-09 23:14:59 +00:00
