Hi all, I'm stuck with a little dilemma and I thought someone could give me a little advice. Is there a way to use rsync with an ssh certificate? what I have: ---------------- First of all I am forced to use the root account with ssh which I know is a big no, no, but sometimes it can't be helped. Second, I need to use a certificate without a password as root which is even worst than

hello, I have a following problem while using rsync: rsync: connection unexpectedly closed (0 bytes read so far) rsync error: error in rsync protocol data stream (code 12) at io.c(189) it was coused by command rsync -r source/ dest/ -e rsh I use rsync-2.6.0 with rsh. What bothers me is that folowing problem apears time to time. I already checked the location of rsync on both machines, both

We''re using some X4540s, with OpenSolaris 2008.11. According to my testing, to optimize our systems for our specific workload, I''ve determined that we get the best performance with the write cache disabled on every disk, and with zfs:zfs_nocacheflush=1 set in /etc/system. The only issue is setting the write cache permanently, or at least quickly. Right now, as it is,

Hi, is there a way in Centos to find out if the Intel turbo mode will be used? Using the 'stress' utility and checking the frequency with cpupower tells me that a CPU is running at it?s maximum frequency as reported by cpupower --- and this frequency is less than the frequency it would run at if it used the turbo mode. All the other CPUs are at their minimum frequency. I have verified

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

Sorry for the off-topic question. I''m needing to replace a disk in a x4540 zfs file system. I have replacement ST31000NSSUN disks, but it''s not obvious to me how to separate the original disk from its drive sled, it seems to be attached by more than the usual 4 screws. Is it meant to be separated? I''ve looked the x4540 user guide but it does not say anything about it.

Hi list, I'm using C7 and noticed that cpu freq is enabled with governor conservative. I've used cpupower utils for governor change, but at the next boot it restart with conservative governor. I've tried also to start cpupower service and setting OPT in /etc/sysconfig/cpupower but it does not works. Can someone point me in the right direction? Thanks in advance

Oracle have deleted the best ZFS platform I know, the X4540. Does anyone know of an equivalent system? None of the current Oracle/Sun offerings come close. -- Ian.

Hi, while testing some APERF/MPERF semantics I discovered that this feature is enabled in Xen Dom0, but is not reliable. The Linux kernel''s scheduler uses this feature if it sees the CPUID bit, leading to costly RDMSR traps (a few 100,000s during a kernel compile) and bogus values due to VCPU migration during the measurement. The attached patch explicitly disables this CPU capability

Has anyone worked with a x4500/x4540 and know if the internal raid controllers have a bbu? I''m concern that we won''t be able to turn off the write-cache on the internal hds and SSDs to prevent data corruption in case of a power failure. -- This message posted from opensolaris.org

Hello, I''m working with someone who replaced a failed 1TB drive (50% utilized), on an X4540 running OS build 134, and I think something must be wrong. Last Tuesday afternoon, zpool status reported: scrub: resilver in progress for 306h0m, 63.87% done, 173h7m to go and a week being 168 hours, that put completion at sometime tomorrow night. However, he just reported zpool status shows:

Hi, I'm experimenting with the migration function of virsh. I'm doing the migrate with following commands: virsh migrate --life --persistent --copy-storage-all --verbose --abort-on-error domain qemu+ssh://root@destination/system virsh migrate-setmaxdowntime domain 20000 However sometimes at the end of the migration, the guest isn't started on the destination host. So I'm left

Hi, Basically, I want to preserve some of directories on destination side conditionally and hence, I choose to use --filter option mentioned in rsync man pages. I noticed that --filter option works as expected when I don't have --relative option used but in below case it doesn't work. rsync -avz --relative --delete --filter='H /mydir2' --exclude='- /preserve' mydir1/.

Hi, I was in under impression that rsync 3.0.5/3.0.6 creates all the missing directories in the path but I think I am wrong. Could any one tell me is it possible to create all missing dirs in path at destination side if not exists. Currently, I have been getting below errors. rsync -avz /tmp/mytest/rsync-test/dir-test/parent-dir/ desthost:/tmp/mytest/rsync-test/dir-test/parent-dir/ sending

I posted this problem as a question to this list a while ago and got no reply. I submitted it as a bug, but found that "samba-bugs@samba.org", no longer accepts bug reports, even though the web page says to send them to that address. Wondering if the option had been intentionally discontinuted without updating the man page, I made a quick check of the source and found that the "-p

Passing the -t option to rsync seems to cause -v to show each directory that is considered, while -v without -t doesn't. Is this a known bug or intended feature? Or is there a way to defeat this? I'd like -v to show the files transmitted, but not the directories that were considered. This command: rsync -urzCv ./ desthost:/path ...shows only the files transferred. While this
