Re: [zfs-discuss] ZFS Usability issue : improve means of finding ZFS<->physdevice(s) mapping

2006-10-13 Thread Noel Dellofano
I don't understand why you can't use 'zpool status'? That will show the pools and the physical devices in each and is also a pretty basic command. Examples are given in the sysadmin docs and manpages for ZFS on the opensolaris ZFS community page. I realize it's not quite the same command

I can also reproduce this on my test machines and have opened up CR 6475506 panic in dmu_recvbackup due to NULL pointer dereference to track this problem. This is most likely due to recent changes made in the snapshot code for -F. I'm looking into it... thanks for testing! Noel On Sep 26, 2

Re: [zfs-discuss] ZFS and very large directories

2006-08-24 Thread Noel Dellofano
ZFS actually uses the ZAP to handle directory lookups. The ZAP is not a btree but a specialized hash table where a hash for each directory entry is generated based on that entry's name. Hence you won't be doing any sort of linear search through the entire directory for a file, a hash is g

I've filed a bug for the problem Tim mentions below. 6463140 zfs recv with a snapshot name that has 2 @@ in a row succeeds This is most likely due to the order in which we call zfs_validate_name in the zfs recv code, which would explain why other snapshot commands like 'zfs snapshot' will fai

Your suspicions are correct, it's not possible to upgrade an existing raidz pool to raidz2. You'll actually have to create the raidz2 pool from scratch. Noel On Aug 2, 2006, at 10:02 AM, Frank Cusack wrote: Will it be possible to update an existing raidz to a raidz2? I wouldn't think s

ZFS doesn't demand that the drives have the same capacity. If you mirror a 30GB drive and a 40GB drive then ZFS will treat them as two 30GB drives, so you're effectively wasting 10GB of space. Noel ** "Question all
