After looking through the archives I haven''t been able to assess the reliability of a backup procedure which employs zfs send and recv. Currently I''m attempting to create a script that will allow me to write a zfs stream to a tape via tar like below. # zfs send -R pool at something | tar -c > /dev/tape I''m primarily concerned with in the possibility

Hi guys, we are proposing a customer a couple of X4500 (24 Tb) used as NAS (i.e. NFS server). Both server will contain the same files and should be accessed by different clients at the same time (i.e. they should be both active) So we need to guarantee that both x4500 contain the same files: We could simply copy the contents on both x4500 , which is an option because the "new

I have an OpenSolaris snv_105 server at home that holds my photos, docs, music, etc, in a zfs pool. I backup my laptops with rsync to the OpenSolaris server. All of my important data is in one place, on the OpenSolaris server. I want to backup this data. I want to protect against losing my data, and I would also like to recover previous versions of files when I make mistakes. * I do not have a

Using build 70, I followed the zfsboot instructions at http:// www.opensolaris.org/os/community/zfs/boot/zfsboot-manual/ to the letter. I tried first with a mirror zfsroot, when I try to boot to zfsboot the screen is flooded with "init(1M) exited on fatal signal 9" Than I tried with a simple zfs pool (not mirrored) and it just reboots right away. If I try to setup grub

Hello all, I''d like to report a tricky situation and a workaround I''ve found useful - hope this helps someone in similar situations. To cut the long story short, I could not properly mount some datasets from a readonly pool, which had a non-"legacy" mountpoint attribute value set, but the mountpoint was not available (directory absent or not empty). In this case

This may be a bit poorly thought through but in this case I don''t really know enough to really think it through. My back ground is linux... there I used a tool called rsnapshot which used rsync and some hardlink magic to create versioned backups. But take very little space. By versioned I don''t mean as in version control but just copies of files as they change. It worked by

Apologies up front for failing to find related posts... Am I overlooking a way to get ''zfs send -i fs at 0 fs at 1 | zfs receive -n -v ...'' to show the contents of the stream? I''m looking for the equivalent of ufsdump 1f - fs ... | ufsrestore tv - . I''m hoping that this might be a faster way than using ''find fs -newer ...'' to learn

Today I attempted to upgrade to S10_U2 and migrate some mirrored UFS SVM partitions to ZFS. I used Live Upgrade to migrate from U1 to U2 and that went without a hitch on my SunBlade 2000. And the initial conversion of one side of the UFS mirrors to a ZFS pool and subsequent data migration went fine. However, when I attempted to attach the second side mirrors as a mirror of the ZFS pool, all

Hi all, What is the current preferred method for backing up ZFS data pools, preferably using free ($0.00) software, and assuming that access to individual files (a la ufsbackup/ufsrestore) is required?

Hello ZFSland, Is there any significance in the fact that the bandwidth/read figures for a simple cpio into a ZFS filesystem should be multiples of 21.3K (when non-zero) as follows? What could determine this figure? Do I need to read a manpage? ;-) Thanks... Sean. ----- [root at global:/36g2] # zpool iostat 3 capacity operations bandwidth pool used avail read

Friends, I have recently built a file server on x2200 with solaris x86 having zfs (version4) and running NFS version2 & samba. the AIX 5.2 & AIX 5.2 client give error while running command "cp -R <zfs_nfs_mount_source> <zfs_nfs_mount_desticantion> as below: cp: 0653-440 directory/1: name too long. cp: 0653-438 cannot read directory directory/1. and the cp core dumps in

Hi all, I have a situation where I need to consolidate a few servers running Solaris 9 and 8. If the application doesn''t run natively on Solaris 10 or Nevada, I was thinking of using Solars 9 or 8 branded zones. My intent would be for the global zone to use ZFS boot/root; would I be correct in thinking that this will be OK for the branded zones? That is, they don''t care about

Hi, If I add an entire disk to a new pool by doing "zpool create", is this reversible? I.e. if there was data on that disk (e.g. it was the sole disk in a zpool in another system) can I get this back or is zpool create destructive? Joubert This message posted from opensolaris.org

Hi, I hope there''s someone here who can possibly provide some assistance. I''ve had this read problem now for the past 2 months and just can''t get to the bottom of it. I have a home snv_111b server, with a zfs raid pool (4 x Samsung 750GB SATA drives). The motherboard is a ASUS M2N68-CM (4 SATA ports) with an Athlon LE1620 single core CPU and 4GB of RAM. I am using it

Apparently with zfs boot, if the zpool is a version grub doesn''t recognize, it merely ignores any zfs entries in menu.lst, and apparently instead boots the first entry it thinks it can boot. I ran into this myself due to some boneheaded mistakes while doing a very manual zfs / install at the summit. Shouldn''t it at least spit out a warning? If so, I have no issues filing a

I would have thought that the file movement from one FS to another within the same pool would be almost instantaneous. Why does it take to platter for such a movement? # time cp /tmp/blockfile /pcshare/1gb-tempfile real 0m5.758s # time mv /pcshare/1gb-tempfile . real 0m4.501s Both FSs are with compression=off. /tmp is RAM. -devsk -- This message posted from opensolaris.org

Bellow, follows a proposal for a new opensolaris project. Of course, this is open to change since I just wrote down some ideas I had months ago, while researching the topic as a graduate student in Computer Science, and since I''m not an opensolaris/ZFS expert at all. I would really appreciate any suggestion or comments. PROJECT PROPOSAL: ZFS Compression Algorithms. The main purpose of
