similar to: How to survive from connection loss with durable file handle

Hi, I am not sure if I am addressing to the correct audience. So apologize for the that. I found in the existing smbtorture test suit do not have much test cases related to durable handle version 2 that is supported for SMB version 3 . I have done some work on that and would like to contribute on that filed. Can anyone let me know the process for that? Thanks in advance, Santanu

Will a write(2) to a ZFS file be made durable atomically? Under the hood in ZFS, writes are committed using either shadow paging or logging, as I understand it. So I believe that I mean to ask whether a write(2), pushed to ZPL, and pushed on down the stack, can be split into multiple transactions? Or, instead, is it guaranteed to be committed in a single transaction, and so committed atomically?

Hello to everyone Durable file handles allow a connection to an SMB server to survive a short network outage. An ongoing IO will continue after the client reconnects to the same server (maybe a difference smbd process if the CTDB status is always health during the outage). When crossing nodes caused by virtual IP’s relocating, durable handles will not work apparently. CA feature in SMB3 works

Hello Ralph, thanks for the info. I have find out that "durable handles" should be available in Samba 4.11, and actually it seems to recognize the share option: durable handles = yes Do you know if any other steps are needed to setup that feature, or could you point me any doc that help to achieve that?

Yes, I saw that they are different I was just willing to test something similar. Actually, I'm searching for a Samba feature that allow transparent failover, or continuos availablity in a cluster setup (Samba + ctbd + gluster) Based on the following link my understanding is that such feature is not currently available in Samba:

hi Michael： We want to implement the ‘persistent handle’ function under Windows 7(SMB 2.1), which has only local ‘durable handle’. For now my plan is just to synchronize the following files between cluster nodes: smbXsrv_open_global.tdb.0 smbXsrv_session_global.tdb.0 smbXsrv_tcon_global.tdb.0 locking.tdb.0 It probably won’t be completed, so I’m writing to ask for your advice. Any help would be

Hi friends, I haven't done such a simulation before and any help would be greatly appreciated. I need your guidance. I need to simulate end to end data for Reliability/survival analysis of a Pump ,with correlation in place, that is at 'Transactional level' or at the granularity of time-minutes, where each observation is a reading captured via Pump's sensors each minute. Once

Hello, We have setup ctdb+Samba v 4.11.1 and testing with Windows client and failover works mostly ok. However when using regular Windows file copy, the copy operation is interrupted during ip takeover. Is there any solution to make the failover transparent to Windows file copy ? I understand that SMB2 durable handles should not be used in a clustered setup, and SMB3 persistent handles +

Hi all, I want to use my * box to control entry to a building. I was wondering who else has done this and what phones they might recommend. The phone itself needs to be externally mounted so will have to be durable. Functionally I would like it to just dial and extension when picked up. Any comments on your experiences would be very much appriciated. Best regards Matt

Thanks very much, Volker. I want to synchronize three tdb files(listed as below) which is relevant to the opened file: 1) brlock.tdb 2) locking.tdb 3) smbXsrv_open_global.tdb These three tdb files are used to realize the durable file handle feature. As what you have said, the performance will be affected if storing these three files in the shared storage. So can I realize the synchronization

A small example data set that illustrates your question will be of great value to those trying to help. This appears to be a transformation that you are wanting to do (timestamp to units of time) so a data representing what you have (dput() is handy for this) and one representing what you want to have with any guidance regarding how to use the other columns in you data set (e.g., the event(0/1)).

Hi guys, I am following this[1] tutorial to install clang. However, I have made a small change in the configure command, and I am running it with '--enable-optimized' option to avoid the debug build. I am getting the errors (given at the end) related to *undeclared identifiers '__NR_*'*. Can someone please provide some input about how to tackle this issue? On my other machine, I

Mark, Below is the sampled simulated granular data format for pumps for trial period of 3 months that I need to transform for survival analysis: 3 months = (60*24*90) minutes i.e 129600 minutes pump_id timings events vibration temprature flow pump1 01-07-2017 00:00 0 3.443 69.6 139.806 pump1 01-07-2017 00:10 1 0.501 45.27 140.028

In principle what you need to do is the following: - break down the time you wish to simulate into intervals. - for each interval, and each failure mode, determine the probability of an event. Determining the probability is the fun part, where you make your domain knowledge explicit and include all the factors into your model: cumulative load, failure history, pressure, temperature,

Thanks Boris and Bret, I was successful in simulating granular/transactional data. Now I need some guidance to transform the same data in format acceptable for survival analysis i.e below format: pump_id | event_episode_no. | event(0/1) | start | stop | time_to_dropout The challenge I'm experience is to generate the 'start' and 'stop' in units of minutes/days from single

Hello, we have a Gluster FS mounted at some /mnt/... path on a Server. The actual physical device behind this resides on some other Server. Now, the requirement is to write files to this Gluster FS Volume in a durable fashion, i.e. for an officially succeeded write the contents MUST have been actually synced to disk on at least one of the Gluster FS nodes in the replica set. Our questions: 1.

I noticed that the Supermicro X9SCL has a USB type-a port right on the motherboard. http://www.supermicro.com/products/motherboard/Xeon/C202_C204/X9SCL.cfm Has anyone used a port like this to boot the core OS and used the physical drives for OpenVZ and KVM containers? I figure a 64GB thumb drive would work. Anyone done this or will a USB thumb drive not stand up too the load? Seems much

Hi, I am curious to know about LLVM IR as platform independent feature. I have compiler some C and C++ applications that compiled on Linux 64bit machine, now I want to generate bit code file on Windows 64bit machine. 1) Will this execute without any issues? 2) Do I pass any option for making it operating system portable? 3) Can I generate bit code file also on Linux machine and then run on
