Re: [zfs-discuss] ZFS layout recommendations

2007-11-27 Thread Tommy McNeely 
The question is, if you *temporarily* migrate your zones to UFS to install the 
big bad S10u4 patch, and migrate back to ZFS afterwards, will patches work 
after that? A better way to say that is, have we resolved this patch problem 
with zoneroot on zfs for S10u4?

[zfs-discuss] cannot import 'rpool': one or more devices is currently unavailable

2009-10-22 Thread Tommy McNeely 
I have a system who's rpool has gone defunct. The rpool is made of a 
single disk which is a raid5EE made of all 8 146G disks on the box. 
The raid card is the Adaptec brand card.  It was running nv_107, but its 
currently net booted to nv_121. I have already checked in the raid card 
bios, and it says the volume is optimal . We had a power outage in 
BRM07 on Tuesday, and the system appeared to boot back up, but then went 
wonky. I power cycled it, and it came back to a grub prompt cause it 
couldn't read the filesystem.

zdb: can't open 7197437773913332097: No such device or address

I obviously have no clue how to weild zdb.

Any help you can offer would be appreciated.

Thanks,

[zfs-discuss] default child filesystem quota

2009-10-26 Thread Tommy McNeely 
I may be searching for the wrong thing, but I am trying to figure out a way to 
set the default quota for child file systems. I tried setting the quota on the 
top level, but that is not the desired effect. I'd like to limit, by default, 
newly created filesystems under a certain dataset to 10G (for example). I see 
this as useful for zfs home directories (are we still doing that?), and 
especially for zone roots. I searched around a little, but couldn't find what I 
was looking for. Can anyone lead me in the right direction?

Thanks in advance,
Tommy
