Re: rsync is concatenating the files together
I am seeing a really odd problem with Rsync 2.6.2 and 2.6.3. I am trying to rsync a directory containing some 2gb files from a Solaris 9 NFS server to a Solaris 10b69 NFS client. Rsync is running on the Solaris 10 client. I'm wondering perhaps if this is more a Solaris 10b69 bug than an rsync bug? Any thoughts on this? I found this message in the archives when investigating a similiar problem I was having with Solaris 10 B69. I have found out some more information that may be helpful. I have four systems running Solaris 10 B69 currently. Of these, only two have encountered strange behavior such as rsync dying, corrupting files, mixing files together, or hanging altogether. The other two systems can run rsync without any problems. Oddly enough the problem occurs on both sparc and x86 systems. The only common factor I could find was that the systems that did not have problems were single CPU systems. The x86 box with the problem was also single CPU, but it is a hyperthreaded cpu so it looked like two to the system. With that in mind, I tried disabling all but one CPU by using the psradm command. After the system had only one cpu active, rsync ran perfectly without error every time. Turn back on the extra CPUs, and the random behavior immediately returned. On the x86 box I just disabled hyperthreading which is no big deal, but the sparc box has four real CPUs, so I'd lose 3/4 my cpu power going down to just one CPU. Anyways, this seems to point to a bug in SMP on Solaris 10 B69, but on the other hand rsync is the only utility I've had problems with so far. With this in mind, is there any additional advice as to what might be going wrong? -- James Lick -- éåæ -- [EMAIL PROTECTED] -- http://jameslick.com/ -- To unsubscribe or change options: http://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.catb.org/~esr/faqs/smart-questions.html
RE: rsync is concatenating the files together
Wayne, I will try some system call tracing, but as I said in my initial post, I am using NFS, so there shouldn't be any transport cleanliness issues. : Re: rsync is concatenating the files together > > On Thu, Nov 11, 2004 at 05:38:56PM -0600, Werner wrote: > > I'm wondering perhaps if this is more a Solaris 10b69 bug than an > > rsync bug? > > I would imagine so.
