similar to: send/recv over ssh

I?ve spend a few hours reading through the forums and wiki and honestly my head is spinning. I have been trying to study up on either buying or building a box that would allow me to add drives of varying sizes/speeds/brands (adding more later etc) and still be able to use the full space of drives (minus parity? [not sure if I got the terminology right]) with redundancy. I have found the ?all in

Hello, I''m debating an OS change and also thinking about my options for data migration to my next server, whether it is on new or the same hardware. Migrating to a new machine I understand is a simple matter of ZFS send/receive, but reformatting the existing drives to host my existing data is an area I''d like to learn a little more about. In the past I''ve asked about

I''m building another 24-bay rackmount storage server, and I''m considering what drives to put in the bays. My chassis is a Supermicro SC846A, so the backplane supports SAS or SATA; my controllers are LSI3081E, again supporting SAS or SATA. Looking at drives, Seagate offers an enterprise (Constellation) 2TB 7200RPM drive in both SAS and SATA configurations; the SAS model offers

Hi, I have a small question about the depth of scrub in a raidz/2/3 configuration. I''m quite sure scrub does not check spares or unused areas of the disks (it could check if the disks detects any errors there). But what about the parity? Obviously it has to be checked, but I can''t find any indications for it in the literature. The man page only states that the data is being

Assuming in a secure and trusted env, we want to get the maximum transfer speed without the overhead from ssh. Thanks. Fred -------------- next part -------------- An HTML attachment was scrubbed...

First, it fails because the destination directory doesn''t exist. Then it fails because it DOES exist. I really expected one of those to work. So, what am I confused about now? (Running 2008.11) # zpool import -R /backups/bup-ruin bup-ruin # zfs send -R "zp1 at bup-20090222-054457UTC" | zfs receive -dv bup-ruin/fsfs/zp1" cannot receive: specified fs (bup-ruin/fsfs/zp1)

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

I''ve tried ssh blowfish and scp arcfour. both are CPU limited long before the 10g link is. I''vw also tried mbuffer, but I get broken pipe errors part way through the transfer. I''m open to ideas for faster ways to to either zfs send directly or through a compressed file of the zfs send output. For the moment I; zfs send > pigz scp arcfour the file gz file to the

Hi all I have this server with some 50TB disk space. It originally had 30TB on WD Greens, was filled quite full, and another storage chassis was added. Now, space problem gone, fine, but what about speed? Three of the VDEVs are quite full, as indicated below. VDEV #3 (the one with the spare active) just spent some 72 hours resilvering a 2TB drive. Now, those green drives suck quite hard, but not

I''m playing around with snv_128 on one of my systems, and trying to see what kinda of benefits enabling dedup will give me. The standard practice for reprocessing data that''s already stored to add compression and now dedup seems to be a send / receive pipe similar to: zfs send -R <old fs>@snap | zfs recv -d <new fs> However, according to the man page,

I'm installing Centos 5.5 on a new Dell R301 server. I wanted to run Xen and have the full virtualization possibilities (this is our development support server, so it runs a few real services and is available for playing with things; putting the "playing with things" functions into virtual servers would protect the "few real services", and make it easier to clean up

I was recently evaluating much the same question but with out only a single pool and sizing my disks equally. I only need about 500GB of usable space and so I was considering the value of 4x 250GB SATA Drives versus 5x 160GB SATA drives. I had intended to use an AMS 5 disk in 3 5.25" bay hot-swap backplane. http://www.american-media.com/product/backplane/sata300/sata300.html I priced

If I type "xm console 6", say (when I have a virtual machine 6 running), what should I get? The documentation seems to indicate that I should get something that behaves like a telnet to a serial console. What I actually get is a connection that might show me a couple of lines of output that do look like they belonged on the console, but doesn't seem to accept any input (except that

Is there an easy way to find out what datasets have dedup''d data in them. Even better would be to discover which files in a particular dataset are dedup''d. I ran # zdb -DDDD which gave output like: index 1055c9f21af63 refcnt 2 single DVA[0]=<0:1e274ec3000:2ac00:STD:1> [L0 deduplicated block] sha256 uncompressed LE contiguous unique unencrypted 1-copy size=20000L/20000P

If I can log in to the guest through the console, I can of course find out what IP DHCP has assigned it. If I configure a static IP I can of course connect to the system there (if it runs services, the firewall allows it, all the usual caveats). Does there happen to be any way to determine from dom0 what IPs are participating in the network and which guests they belong to? (I'm configuring

Greetings, Quick question: I am about to acquire some disks for use with ZFS (currently using zfs-fuse v0.7.0). I''m aware of some 4k alignment issues with Western Digital advanced format disks. As far as I can tell, the Hitachi Deskstar 7K3000 (HDS723030ALA640) uses 512B sectors and so I presume does not suffer from such issues (because it doesn''t lie about the physical layout

Hi All, I am looking at ZFS and I get that they call it RAIDZ which is similar to RAID 5, but what about RAID 10? Isn''t a RAID 10 setup better for data protection? So if I have 8 x 1.5tb drives, wouldn''t I: - mirror drive 1 and 5 - mirror drive 2 and 6 - mirror drive 3 and 7 - mirror drive 4 and 8 Then stripe 1,2,3,4 Then stripe 5,6,7,8 How does one do this with ZFS?

I built a fileserver on solaris 10u6 (10/08) intending to back it up to another server via zfs send | ssh othermachine ''zfs receive'' However, the new server is too new for 10u6 (10/08) and requires a later version of solaris . presently available is 10u8 (10/09) Is it crazy for me to try the send/receive with these two different versions of OSes? Is it possible the
