I compiled SPEC CPU2006 bzip2 with Clang, and generated profiles with OPT's -insert-optimal-edge-profiling option. After a profile run, I launched OPT with -profile-loader -profile-verifier flags and also passed -O3 flag. This caused OPT to give a warning "WARNING: profile information is inconsistent with the current program!" and then fail with an assert (ASSERT:inWeight and

Dear OpenSSH Community, Please find an experimental patch for resilient SSH connections from the web page below. It enables an SSH session to continue over sequential TCP connections in case of a broken TCP connection or change of an IP address. The page also includes the related USENIX'06 paper which describes the design in detail. http://www.infrahip.net/resilient/ Best regards,

Hi guys, I don't mean to incite debate or something, just want to share experience and a little curiosity. Back long time ago, we have an old file MS W2K (NTFS) server where due no admin was available to manage it, the server would get power off when the office closed, and auto power on again in the morning. That thing happened for years and it was fine ^^ Recently, I setup a Centos 5.5 file

This series fixes two cases where behavior on secure boot errors could be improved: 1) Patch 2 propages secure-boot errors from GR init, making sure initialization fails as it should. Failure to do so results in a black screen during boot, as reported in FD bug 94990. 2) Patches 3-4 make the absence of required secure firmware files a non-fatal error. The previous behavior was to give up

You can do it using replication, https://wiki.dovecot.org/Replication but since you have no staging/test environment, I would advice you to get one.

Hello, you need to "clone" the first server, change the ip address, mount the same maildir storage and use some mechanism to share the accounts database. Then you need to put a TCP load-balancer in front of the servers an you are good to go. This is the easiest solution if you already have in the network an appliance that can do LB. For instance if you already have a firewall with

Hello folks, I have been asked about the resilience of samba clients when faced with a domain controller failure. My client's environment has multiple Windows Domain Controllers (we'll call them dc1 - dc9). Assuming that domain replication operates as expected (and does, from Windows workstation point of view), what should I expect if (when) the domain controller that initiated a

Hi, I am using theora codec to stream video. Sometimes I am getting (due network actions- packet loss / delay) a distortion in the video image degrading its quality and I think it is something related to the video slices / chunks (dropped or disordered) of the entire frame. Are there plans for slicing and loss detection/resilience built-in theora codec? Will theora codec have a similar approach

Yes, but it works for small systems if you set IP source address persistence on LB or even better, if you set priority to be Active/Standby. I couldn't find a good example with dovecot director and backend on the same server, so adding another two machines seems overkill for small setups. If someone has a working example for this please make it public ! Quote from

Hello, 1) If i create a raidz2 pool on some disks, start to use it, then the disks'' controllers change. What will happen to my zpool? Will it be lost or is there some disk tagging which allows zfs to recognise the disks? 2) if i create a raidz2 on 3 HDs, do i have any resilience? If any one of those drives fails, do i loose everything? I''ve got one such pool and
