Package: zfs-fuse
Version: 0.7.0-12
Severity: important
Tags: upstream patch
Dear Maintainer,
I see exactly the behavior described in
https://groups.google.com/forum/#!topic/zfs-fuse/-BtjGFUPOyk:
Removing the com.sun:auto-snapshot-desc property as descibed in the
command by user hornowitz did not help for me, though.
# zfs list -r -t snapshot -H zpool | wc -l
504
# zdb -d zpool | grep "^Dataset .*@" | wc -l
913
I can list any property of the missing snapshots if I name the snapshot
on the command line, it exists but is just missing in the output of "zfs
list -t snapshot <fs>".
After some debugging, I found the root cause in src/lib/libzfs/libzfs_dataset.c:
2425 static int
2426 zfs_do_list_ioctl(zfs_handle_t *zhp, int arg, zfs_cmd_t *zc)
2427 {
2428 int rc;
2429 uint64_t orig_cookie;
2430
2431 orig_cookie = zc->zc_cookie;
2432 top:
2433 (void) strlcpy(zc->zc_name, zhp->zfs_name, sizeof (zc->zc_name));
2434 rc = ioctl(zhp->zfs_hdl->libzfs_fd, arg, zc);
2435
2436 if (rc == -1) {
2437 switch (errno) {
2438 case ENOMEM:
2439 /* expand nvlist memory and try again */
2440 if (zcmd_expand_dst_nvlist(zhp->zfs_hdl, zc) != 0) {
2441 zcmd_free_nvlists(zc);
2442 return (-1);
2443 }
This code assumes ioctl() returns either 0 or -1, but I'm occasionally getting
12 (=ENOMEM) here. After changing the condition in line 2436 to just "if (rc)"
and recompiling the zfs command the output of "zfs list -r -t snapshot" matches
the output of zdb.
Kind regards,
Michael
