similar to: Network Performance Update

One of our summer interns has stayed on working part time on weekends during the school year.? This schedule presents an opportunity for technical investigations and some needed performance testing.? The last weekend assignment included data rate testing on one specific network pathway. Checking out previous network testing was the first assignment. Some five year old, archived SPARC/Solaris and

HI , I setup vsftp yesterday as a local user only mode. No anonymous was enabled. I set up this vsftpd on my machine running CentOS 4.4. its ip is 192.168.101.25. so when I login as ftp://192.168.101.25/ via web browser, I am promted the username as password. After inputing username and password, I can login successfully. Then I can download everything as usual. But I can not upload any data ?

When I use the preallocate patch and create a 77GB file using the function I get a CPU spike on the server-side. The spike lasts about 20 minutes and uses about 20%-25% of the cpu associated with the rsync instance creating the file. The spike is directly linked to the time it takes to create the file. I compiled rsync using cygwin CVS. I initially suspected the implementation of

Hi I'm trying to setup a 3 node gluster, and am hitting huge performance bottlenecks. The 3 servers are connected over 10GB and glusterfs is set to create a 3 node replica. With a single VM performance was poor, but I could have lived with it. I tried to stress it by putting copies of a bunch of VMs on the servers and seeing what happened with parallel nodes.. network load never broke

Last friday we upgraded from 1.9.17p4 to version 1.9.18p3 on a HP-UX 9.04 machine. Now we get lots of entries in the log.smb file like: ERROR: del_share_mode: failed to ftruncate share mode file /programs/samba/var/locks/share.1073807365.8199 to size 42 (Permission denied) ERROR: set_share_mode: failed to ftruncate share mode file /programs/samba/var/locks/share.1073807365.8195 to size 42

Thank you for the information that you have passed on to me. My own research has found that ftruncate is quite happy to set a file to the same size that it is already, so something else must be causing the problem. The comment before the ftruncate in set_share_mode says the file is being truncated just for safety, so normally it is probably not necessary to truncate the file. Regards, Tim >

Hi, I'm running Samba 3.0.23a on Linux. One of my share is a USB disk with a FAT32 filesystem. When copying large files from my Windows XP machine to this share, smbd seem to "reserve" (by using ftruncate()) the space needed on the USB disk before actually doing any copying. This ftruncate() operation takes quite a while when the file is large. It may even cause the client to time

I''m running SunOS unknown 5.11 snv_33 i86pc i386 i86pc and to print a blank line in the output of my script I tried adding: trace(""); which printed 0 1 2 3 4 5 6 7 8 9 a b c d e f 0123456789abcdef 0: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 10: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

I added debuging as follows: /* no O_EXCL, existence check is via the fcntl lock */ lockfile_fd = open(lockfile_name.buf, O_NONBLOCK|O_CREAT|O_WRONLY, 0644); if (lockfile_fd == -1) { ret = errno; DEBUG(1, ("%s: open failed: %s\n", __func__, strerror(errno))); return ret; }

If your system does not support fallocate(2), we use ftruncate(2) to create an output file. fallocate(2) succeeds even if your disk have less space than the requested size, because it creates a sparse file. If you mmap such sparse file, you'll receive a SIGBUS when the disk actually becomes full. So, lld can die suddenly with SIGBUS when your disk becomes full, and currently we are not doing

Samba 1.9.17p1.

I've been running some tests on files created by rsync and noticing fragmentation issues. I started the testing because our 5TB array started performing very slowly and it appears fragmentation was the culprit. The test I conducted was straighforward: 1. Copy over a 49GB file. Analyzed with contig (from sysinternals), no fragments. 2. Ran rsync and the file was recreated normally (rsync

I use fedora 7 and the last stable version of samba 3.0.25a-3 on an embedded linux system as a server and a windows xp. I 'am using truecrypt and sharing de mount directory with the XP machine via samba. Selniux is disabled. Everything works well such as connection or small files transfers but we have a huge problem when we try to transfer a big file (~100 MB) from the client (Windows) to the

I am trying to see if Samba 4.2.0rc4 will run on a Solaris 10 i386 system. After getting it to build, startup fails. Starting it up as smbd -i -d 10 The output indicates that everything is starting normally until the following is output: messaging_dgm_lockfile_create: ftruncate failed: Invalid argument messaging_dgm_init: messaging_dgm_create_lockfile failed: Invalid argument messaging_dgm_init

Hiya, I can see it's a regular subject on this list. I, like others wanted to use rsync to synchronise two block devices (as it happens one lvm volume and one nbd device served by qemu-img on a remote host from a qcow2 disk image so that I can keep the old versions) As I couldn't find any report of it being done successfully, I'm just sharing my findings as it might benefit others.

When I combine separate vectors into one list, there are new names created. I'd like to change them to something more meaningful.

Hi, So is the KVM or Vmware as the host(s)? I basically have the same setup ie 3 x 1TB "raid1" nodes and VMs, but 1gb networking. I do notice with vmware using NFS disk was pretty slow (40% of a single disk) but this was over 1gb networking which was clearly saturating. Hence I am moving to KVM to use glusterfs hoping for better performance and bonding, it will be interesting to see
