atomicthumbs posted:this is disturbing, to me at top-level*, it's less weird than it sounds. the mainframe libraries that applications use to talk to disks are essentially database APIs. like ibm vsam, the successor to the ibm isam of yore https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.1.0/com.ibm.zos.v2r1.idag200/vsam.htm this presents an isam api that is similar to microsoft isam aka esent aka "jet blue," because microsoft isam was directly inspired by the old ibm isam. the engine -- https://en.wikipedia.org/wiki/Extensible_Storage_Engine the c# api -- https://managedesent.codeplex.com/wikipage?title=PersistentDictionaryDocumentation&referringTitle=Home *at low levels it gets weird as gently caress again. for historical reasons, mainframe disks don't speak regular scsi, and don't have sectors / cylinders. instead they are "ckd" -- count, key, data. the disk commands themselves operate on isam-lookin' record structures! https://en.wikipedia.org/wiki/Count_key_data

Star War Sex Parrot posted:it had certainly fallen behind. it really needed to go once Apple became almost NAND-storage exclusive. at that point it made no sense not to be aping stuff from F2FS. rumor had it that the iOS team had internally forked HFS+ which certainly seemed untenable for the long term. if you're gonna start over, you might as well grab stuff from btrfs and zfs while you're at it From what I heard, it wasn't really that it was forked, they were just using HFS+ with Case Sensitivity turned on and some jiggery-pokery with volumes to isolate the OS from the user data (it's how you can wipe the user data off a device instantly but not touching iOS) Their justification for only checksumming the metadata has been 'well, we do so much checksumming closer to the metal with our flash controllers, so adding in another level on top of it won't really get you any benefits'.

hey shaggar since you seem to know so much about NTFS can you tell me whether this is optimal or notpre:MFT Information --------------- MFT size : 8691 MB (3% of drive)

probably not. how many files do u have on there?

Shaggar posted:probably not. how many files do u have on there? turns out the Linux for Windows subsystem had generated 7.5 million files in a temp folder, which is 15 times more files than the rest of the drive has in it. deleting them took a couple hours. the MFT was still huge after that but i got paragon hard disk manager suite 15 or something which is apparently the only tool able to do any sort of compacting operation on the MFT and now my poo poo's much faster and my MFT is only 455 megabytes

any of y'all have experience with distributed filesystems? i'm talkin xtreemfs, ceph, and so on. interest is mainly in something to put on a strong NAS that'll act like block storage but can be accessed from both linux and windows over a 10gb link, and be accessed by more than one computer at once

I used to use the Andrew File System over 10Base-T on a DECstation 3100 with only 8MB RAM and 80MB local disk (for Ultrix bootstrapping, the AFS object cache, and swap space), it was decent and the filesystem never felt like the bottleneck I'm sure the state of distributed file systems has only improved in the 20+ years since then

When this happens again you can use robocopy /purge with an empty directory as the source. Stuff that makes explorer crash only takes seconds this way.

if you mean one giant share to be accessed by everyone then there’s nothing wrong with smb and nfs. there’s no reason to have it as block storage since Linux and windows and everything else support both natively
