Re: [zfs-discuss] Restore a ZFS Root Mirror

2008-09-13 Thread Ivan Wang
my hunch is you need to boot from live cd (in virtual box case, iso) and installgrub -m /boot/grub/stage1 /boot/grub/stage2 $diskB_root_slice Ivan. Currently grub hasn't been installed for disk attached to root mirror later. Hi all, after installing OpenSolaris 2008.05 in VirtualBox I've

Re: [zfs-discuss] ZFS and acl questions in Indiana

2007-12-20 Thread Ivan Wang
What does 'which chmod' show? I think that Indiana chose to have /usr/gnu/bin at the head of the path, so you're probably picking up the GNU chmod, which doesn't handle NFSv4 ACLs. Manually running /usr/bin/chmod should solve your problem. Would it be better if this issue is brought to

[zfs-discuss] enlarge a mirrored pool

2007-10-12 Thread Ivan Wang
Hi all, Forgive me if this is a dumb question. Is it possible for a two-disk mirrored zpool to be seamlessly enlarged by gradually replacing previous disk with larger one? Say, in a constrained desktop, only space for two internal disks is available, could I just begin with two 160G disks,

This bug was rendered moot via 6528732 in build snv_68 (and s10_u5). We now store physical devices paths with the vnodes, so even though the SATA framework doesn't correctly support open by devid in early boot, we But if I read it right, there is still a problem in SATA framework (failing

HI all, Recently zfs boot is delivered in scheduled b62, so is there any words when and how may we use live upgrade with zfs root? Since I only use SXCR now and sometimes you just need to boot to older BE in case of a no-so-good build, live upgrade becomes very handy for me on that. Cheers,
