Re: [zfs-discuss] zfs send/receive as backup - reliability?
+1 for zfsdump/zfsrestore Julian Regel wrote: When we brought it up last time, I think we found no one knows of a userland tool similar to 'ufsdump' that's capable of serializing a ZFS along with holes, large files, ``attribute'' forks, windows ACL's, and checksums of its own, and then restoring the stream in a filesystem-agnostic read/write/lseek/... manner like 'ufsrestore'. This has been something I've been working on for the last few days and I've not yet found an adequate solution. I've looked at tar, cpio and pax as potential tools for backing up a ZFS filesystem to tape, but each has limitations. As of today, Sun do not provide the ability to reliably backup a Solaris installation without resorting to third party tools. This is crazy! The beauty of ufsdump/ufsrestore is that because it's bundled with the operating system, I can perform bare metal recovery using a Solaris DVD and locally attached tape drive. It's simple and arguably essential for system administrators. From my perspective, Sun really need to create a zfsdump/zfsrestore set of commands that perform block level backups of a specified filesystem (or snapshot) and that preserves ACLs, atime, sparse files, handles multiple tapes (many of us still use and rely on tape!) etc. Does anyone know the process to formally request this (we have a support contract), or would I be wasting my time?

Re: [zfs-discuss] zfs root, jumpstart and flash archives
Hello Lori, It has been a while since this has been discussed, and I am hoping that you can provide an update, or time estimate. As we are several months into Update 7, is there any chance of an Update 7 patch, or are we still waiting for Update 8. Also, can you share the CR # that you mentioned in your previous email (below), so I can read further into this? thanks again, Jerry Kemp Lori Alt wrote: Latest is that this will go into an early build of Update 8 and be available as a patch shortly thereafter (shortly after it's putback, that is.

Re: [zfs-discuss] Apple Removes Nearly All Reference To ZFS

[zfs-discuss] boot-interest WAS: Reliability at power failure?
Where is the boot-interest mailing list?? A review of mailing list here: http://mail.opensolaris.org/mailman/listinfo/ does not show a boot-interest mailing list, or anything similar. Is it on a different site? Thanks Richard Elling wrote: Uwe Dippel wrote: C. wrote: I've worked hard to resolve this problem.. google opensolaris rescue will show I've hit it a few times... Anyway, short version is it's not zfs at all, but stupid handling of bootarchive. If you've installed something like a 3rd party driver (OSS/Virtualbox) you'll likely hit this bug. You might have hit the nail on the head. My two candidates could be either Nvidia or VirtualBox. Still, ought boot archive not be an independent process, that creates a proper backup in case of any modification, from any stupid handling? Should a recycling reboot not be noted, if just by a flag (in case we have r/w of a drive), including a redirection of the messages into a file? (Okay, that's off-topic in this list). Should ZFS not keep track of a proper roll-back point to offer to boot to in case of failing/recycling boots? Maybe something like 'last successful boot'? All good points, but not appropriate for this list.

How would this work for servers that support only (2) drives, or systems that are configured to have pools of (2) drives, i.e. mirrors, and there is no additional space to have a new disk, as shown in the sample below. I still support lots of V490's, which hold only (2) drives. Thanks, Jerry Ross wrote: > Gaah, my command got nerfed by the forum, sorry, should have previewed.
