I''m planning on setting up an NFS server for our ESXi hosts and plan on using a virtualized Solaris or Nexenta host to serve ZFS over NFS. The storage I have available is provided by Equallogic boxes over 10Gbe iSCSI. I am trying to figure out the best way to provide both performance and resiliency given the Equallogic provides the redundancy. Since I am hoping to provide a 2TB datastore I am thinking of carving out either 3 1TB luns or 6 500GB luns that will be RDM''d to the storage VM and within the storage server setting up either 1 raidz vdev with the 1TB luns (less RDMs) or...

...rver with Dovecot version 2.2.10. I also installed the postfix(version: 2.6.6) in it. At present it have around 10 domains and each domain is having around 20 email boxes. It has very simple configuration. User's reading the email via some internal applications/Outlook. I would like to create resilience/HA for this environment. Could you please suggest me, what is the easiest way to achieve this? If any one can suggest step by step that will be more helpful to me.

Thank you Aki for the reply. But I cannot disturb the version at present as it is a live server and thousands of emails will circulate every hour. Could you please suggest me how to create HA/resilience for the existing environment. I have another server ready with the similar configuration. Please provide any steps/link for me to proceed on this? It will be a great help to me. Thanks, Kishore On Thu, Jan 9, 2020 at 4:33 PM Aki Tuomi <aki.tuomi at open-xchange.com> wrote: > > &g...

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 i''m afraid it''s a ticking time bomb.

Thank you all for the replies.... I have the test environment with the same configuration. But I have been asked to go with same environment for HA/Resilience in Live. Yes, I have only one Live server. It is configured in "Maildir" format. The data stores on a Network / Shared Storage (But definitely not local disk, its a mount point). I have been asked to create a HA/Resilience for this environment. They gave me another server with same...

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....

...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 like H.264 to deal with the loss of some frame fragments?

...: ( 2 systems) ======================== Linux OS - Red Hat Enterprise Linux Server release 7.7 (Maipo) Dovecot version - 2.2.36 (1f10bfa63) Postfix version - 2.10.1 In the new environment, I have 2 servers. I have got 2 of the above servers with above configuration and need to create HA/Resilience. I know there is advanced versions in Redhat and Dovecot. As per my organisation's existing support/policy, that is what maximum supported RHEL and official version of dovecot as per RHEL 7.7. Now my questions are: 1. I will stop the dovecot/postfix services on the server in old environme...

...ization pass with the profile, then there is no warning/assert in the profile verification. Is this because different passes of -O3 are modifying the CGF that makes it inconsistent with the originally produced profile? Is this expected behavior? Can't we make profiles (and profile verification) resilient to transformations ? -Milind

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 (...

Hi, We're testing CELT (version 0.7.1) error resilience capability. We've used already celtdec packet-loss options. Hence we know what to expect in case of whole packet loss. How does Celt respond to a broken encoded packet? Is it always better to discard it and decode the missing frame through decode_lost? We have the hardware capability of...

On the whole we are pleased with our trials of dovecot to replace UW-IMAP. But (ah!) we have hit one particular problem, in which we think dovecot could probably benefit from a resilience improvement. We're running dovecot on Fedora Core 5 (FC5), with passwd map details supplied by NIS. We have found that "nscd" sometimes thinks that a username is invalid, even though it is valid. So when "deliver" attempts a delivery to the INBOX of that username, it...

Hello What is the expected behavior of winbind on a member server when the AD DC it is communicating with becomes un-responsive? Is this a configurable behavior? Seems we have a 'hang' on authentication requests when we lose one of our DCs and a restart of winbind is our only way out at present Thanks, Rob ---------------------------------------------------------------------- This is
