问题 I was trying below architecture in fabric where one peer is on another machine rest of the network set up in first machine(server/system), after creating channel while adding each peer to the channel shows a log as below which was not the case when i tried sample network, the log used to say peer joined to channel, also when i check the logs of peer it says : 2018-02-28 06:51:23.916 UTC [ConnProducer] NewConnection -> ERRO 36b Failed connecting to 138.68.138.161:7050 , error: x509: cannot

问题 I'm trying to utilize WMI via PowerShell to run through SAN storage on remote servers to grab the Windows disk management volume label. The only way I've found to do this is to correlate the volume device id ( \\?\Volume{34243...} with the physical disk device ID ( \\.\PHYSICALDRIVE01 ). However, I haven't been able to find out how to link those two fields together. Is this possible with WMI? 回答1: For volumes that were assigned a drive letter you can correlate disks and volumes like this: Get

问题 When I researched horizontal scaling for relational databases on the internet, I got the impression that the only option which includes write scaling as well as read scaling is sharding, which seems to be a manual design process that involves complex application specific configurations and is hard to maintain if you need to change your sharding structure. On the other hand, NoSQL seems to be natively supporting horizontal scaling but it has the drawback of not supporting transactions, ACID

问题 We have some old applications that communicate via directory-based queues. Each item in the queue is a file, and there's a header file that maintains an ordered list of the filenames for the items in the queue. Naturally, this old code needs to lock the queue while items are pushed and popped. What it's doing is creating a lock subdirectory, on the assumption that mkdir() is an atomic operation - if multiple processes attempt to create a directory, only one of them is going to succeed. One of

问题 I am contacting you regarding an issue I have with syslog-NG. some of our devices (mainly HP switches and SANs) are sending syslog messages that do not respect the syslog RFC 5424 it seems. to give you a few examples : if I sniff the network interface of the server, we can see these "wrong" messages like that (as you can see, after the PRI, we can see the PROGRAM, then timezone and fields separated with commas. in short, mixed fields, missing fields etc. not a standard syslog message) : <190

问题 Scenario: I am using FSEvents to monitor local watch folders successfully. Using the same FSEVents code to monitor a directory that is within a mounted volume from a remote server over say, AFS (/Volumes/example) successfully notifies my FSEVents callback for any files the local client changes, but not changes made by other users on other machines - even though I do see those changes reflected immediately in the Finder. Heres my FSEvents implementation: DirectoryWatcher.m What I expect to
