[zfs-discuss] ZFS Bad Blocks Handling

2007-08-27 Thread RL
Hi, Does ZFS flag blocks as bad so it knows to avoid using them in the future? During testing I had huge numbers of unrecoverable checksum errors, which I resolved by disabling write caching on the disks. After doing this, and confirming the errors had stopped occuring, I removed the test file

Hello I've got nested ZFS filesystems exported via NFS. They are mounted on the clients using automount (from a NIS map). But: only the root exported filesystem shows any contents on the clients. Any sub-directories it has are fine, but any sub-filesystems are empty. ie. NIS map auto.stuff cont

[zfs-discuss] ZFS-Quota

2007-08-27 Thread Patrik Zeimetz
Hello, it seems that while designing the ZFS-Quota and bringing functionality into it which was not included in the traditional ufs user quota, some of its functionality is missing. In the FAQ is stated: "Per-user quotas were introduced because multiple users had to share the same file system."
