Author: mav Date: Mon Jan 22 04:35:17 2018 New Revision: 328249 URL: https://svnweb.freebsd.org/changeset/base/328249 Log: 8641 "zpool clear" and "zinject" don't work on "spare" or "replacing" vdevs illumos/illumos-gate@2ba5f978a4f9b02da9db1b8cdd9ea5498eb00ad9 https://www.illumos.org/issues/8641: "zpool clear" and "zinject -d" can both operate on specific vdevs, either leaf or interior. However, due to an oversight, neither works on a "spare" or "replacing" vdev. For example: sudo zpool create foo raidz1 c1t5000CCA000081D61d0 c1t5000CCA000186235d0 spare c1t5000CCA000094115d0 sudo zpool replace foo c1t5000CCA000186235d0 c1t5000CCA000094115d0 $ zpool status foo pool: foo state: ONLINE scan: resilvered 81.5K in 0h0m with 0 errors on Fri Sep 8 10:53:03 2017 config: NAME STATE READ WRITE CKSUM foo ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 c1t5000CCA000081D61d0 ONLINE 0 0 0 spare-1 ONLINE 0 0 0 c1t5000CCA000186235d0 ONLINE 0 0 0 c1t5000CCA000094115d0 ONLINE 0 0 0 spares c1t5000CCA000094115d0 INUSE currently in use $ sudo zinject -d spare-1 -A degrade foo cannot find device 'spare-1' in pool 'foo' $ sudo zpool clear foo spare-1 cannot clear errors for spare-1: no such device in pool Even though there was nothing to clear, those commands shouldn't have reported an error. by contrast, trying to clear "raidz1-0" works just fine: $ sudo zpool clear foo raidz1-0 Modified: vendor/illumos/dist/lib/libzfs/common/libzfs_pool.c Modified: vendor/illumos/dist/lib/libzfs/common/libzfs_pool.c ============================================================================== --- vendor/illumos/dist/lib/libzfs/common/libzfs_pool.c Mon Jan 22 04:31:48 2018 (r328248) +++ vendor/illumos/dist/lib/libzfs/common/libzfs_pool.c Mon Jan 22 04:35:17 2018 (r328249) @@ -50,6 +50,7 @@ #include "zfeature_common.h" static int read_efi_label(nvlist_t *, diskaddr_t *, boolean_t *); +static boolean_t zpool_vdev_is_interior(const char *name); #define BACKUP_SLICE "s2" @@ -2072,10 +2073,7 @@ vdev_to_nvlist_iter(nvlist_t *nv, nvlist_t *search, bo break; } - verify(strncmp(type, VDEV_TYPE_RAIDZ, - strlen(VDEV_TYPE_RAIDZ)) == 0 || - strncmp(type, VDEV_TYPE_MIRROR, - strlen(VDEV_TYPE_MIRROR)) == 0); + verify(zpool_vdev_is_interior(type)); verify(nvlist_lookup_uint64(nv, ZPOOL_CONFIG_ID, &id) == 0); @@ -2182,10 +2180,13 @@ zpool_find_vdev_by_physpath(zpool_handle_t *zhp, const /* * Determine if we have an "interior" top-level vdev (i.e mirror/raidz). */ -boolean_t +static boolean_t zpool_vdev_is_interior(const char *name) { if (strncmp(name, VDEV_TYPE_RAIDZ, strlen(VDEV_TYPE_RAIDZ)) == 0 || + strncmp(name, VDEV_TYPE_SPARE, strlen(VDEV_TYPE_SPARE)) == 0 || + strncmp(name, + VDEV_TYPE_REPLACING, strlen(VDEV_TYPE_REPLACING)) == 0 || strncmp(name, VDEV_TYPE_MIRROR, strlen(VDEV_TYPE_MIRROR)) == 0) return (B_TRUE); return (B_FALSE);
