diskspace

问题 I am running a container on a VM. My container is writing logs by default to /var/lib/docker/containers/CONTAINER_ID/CONTAINER_ID-json.log file until the disk is full. Currently, I have to delete manually this file to avoid the disk to be full. I read that in Docker 1.8 there will be a parameter to rotate the logs. What would you recommend as the current workaround? 回答1: Docker 1.8 has been released with a log rotation option. Adding: --log-opt max-size=50m when the container is launched does

问题 So, in many situations I wanted a way to know how much of my disk space is used by what, so I know what to get rid of, convert to another format, store elsewhere (such as data DVDs), move to another partition, etc. In this case I'm looking at a Windows partition from a SliTaz Linux bootable media. In most cases, what I want is the size of files and folders, and for that I use NCurses-based ncdu: But in this case, I want a way to get the size of all files matching a regex . An example regex

问题 There are a lot of system images piling up on my disk in the android sdk folder. i hardly use the emulator. May be once in 6 months. Most of my development is directly on device. What i wanted to check was, will removing the system images (at least for the old APIS i.e. < 22) impact the development? Also, the google apis folder seen below. Should i keep it for all versions or just the one in the latest suffice? Screenshot above is from WinDirStat tool. - https://windirstat.net 回答1: System

问题 The mongodb document says that To compact this space, run db.repairDatabase() from the mongo shell (note this operation will block and is slow). in http://www.mongodb.org/display/DOCS/Excessive+Disk+Space I wonder how to make the mongodb free deleted disk space automatically ? p.s. We stored many downloading task in mongodb, up to 20GB, and finished these in half an hour. 回答1: In general if you don't need to shrink your datafiles you shouldn't shrink them at all. This is because "growing"

问题 Is it possible to get the amount of free memory on an Android device (not on the SD CARD) via the Android SDK?

问题 I'm looking for a better way to detect available/free disk space on the iPhone/iPad device programmatically. Currently I'm using the NSFileManager to detect the disk space. Following is the snippet of the code which does the job for me: -(unsigned)getFreeDiskspacePrivate { NSDictionary *atDict = [[NSFileManager defaultManager] attributesOfFileSystemForPath:@"/" error:NULL]; unsigned freeSpace = [[atDict objectForKey:NSFileSystemFreeSize] unsignedIntValue]; NSLog(@"%s - Free Diskspace: %u

问题 I have some large InnoDB databases, close to 1TB. In order to free up some space while working on an alternative storage, I deleted some unused InnoDB indexes hoping that it would free up some space. It freed nothing. As it's InnoDB, will the engine use the empty allocated space for further inserts and indexing ? Thanks 回答1: InnoDB stores data in a tablespace. By default, there is one single tablespace and data of all the databases is stored in one file. This file has data dictionary, tables,
