You can use vmtouch for this... To see how much of SYSERR.TXT is in the file system cache, [root@GreenLeaf /ppro/data]# vmtouch -v SYSERR.TXT SYSERR.TXT [OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO] 1859/1859 Files: 1 Directories: 0 Resident Pages: 1859/1859 7M/7M 100% Elapsed: 0.000316 seconds 100% of it ...

If you simply want to answer the question, "what files on this system have changed", then use a tool that generates checksums for all your files. Run it before the consultant makes any changes, run it afterwards, and look for files that have changed. Store the results someone other than on the system. And of course, be aware that some files change ...

Had a similar issue with a Dell controller. When the RAID5 virtual disk on the controller is set to write-through, the copy performance issue exists. When the virtual disk is switched to write-back, the problem disappears. You could also try using XCOPY with the /J parameter to use unbuffered IO. This will avoid the file system cache overhead and prevent ...

Journalling in the guest OS can give a false sense of security in case of an unclean shutdown of the host OS. For journalling to work, it is essential that the OS is in control of the order in which data is written to disk. The guest OS may think it is in control, but there is no guarantee that the host OS actually writes the data to disk in the same ...

You don't need long pathnames if you chdir into the directory and just use relative paths to rmdir. Or, if you have a POSIX shell installed, or port this to the DOS equivalent: # untested code, didn't bother actually testing since the OP already solved the problem. while [ -d Folder1 ]; do mv Folder1/Folder1/Folder1/Folder1 tmp # repeat more times to ...

1) Assuming that you boot from some other disk you might just as well put the file system on the raid disk without any partition table. This is if you prefer single big file systems filling up the entire raid disks. If you for some reason want to split up the raid you should of course use a partition table for that. 2) If you feel comfortable with ext4, ...

Java can also deal with long file paths. And it can do it a lot faster too. This code (which I copied from the Java API documentation) will delete a 1600 level deep directory structure in about 1 second (under Windows 7, Java 8.0) and with no risk of stack overflow since it doesn't actually use recursion. import java.nio.file.*; import ...

Not an answer, but I don't have enough rep for a comment. I once fixed this problem on a then-huge 500MB FAT16 disc on an MS-DOS system. I used DOS debug to manually dump and parse through the directory table. I then flipped one bit to mark the recursive directory as deleted. My copy of Dettman and Wyatt 'DOS Programmers' Reference' showed me the way. I ...

Thanks to everyone for the useful advice. Straying well into StackOverflow territory, I've solved the problem by knocking up this snippet of C# code. It uses the Delimon.Win32.IO library that specifically addresses issues accessing long file paths. Just in case this can help someone else out, here's the code - it got through the ~1600 levels of recursion ...

Could be a recursive junction point. Such a thing can be created with junction a file and disk utility from Sysinternals. mkdir c:\Hello junction c:\Hello\Hello c:\Hello And you can now go endlessly down c:\Hello\Hello\Hello.... (well until MAX_PATH is reached, 260 characters for most commands but 32,767 characters for some Windows API functions). A ...

This sounds like a mix up of different principles. A machine named ServerName is sharing a path c:\path\to\sharename which is shared via name sharename. In this scenario, you connect to the share name remotely simply with \\ServerName\sharename - not the whole path of the share name. By default, administrators are also able to access the root of each ...

I am not aware of an application that will do this for you. Your most likely solution is to write a script yourself, it shouldn't really be that difficult. It appears that the source directory is in fact an NFS mount (we don't know what the destination directory is). This means that inotify can't be used. The internet suggests that FAM may be of use in ...

ZFS on Linux uses the usershare feature of samba. So to make this work, you have to enable this in smb.conf by defining a directory for storing the usershare definitions [global] ; directory for storing the usershare definitions. permissions ; of the directory govern who can use this. usershare path = /var/lib/samba/usershares usershare max shares = 100 ...

I have not seen reference to anything like "nofail" in fstab, I would like to. Any mention of a filesystem in fstab has caused boot delay for me, so in my home combined router and filesharing box I did this: I made no reference to my massive A/V share in fstab, so that boot would be rapid and only look at the tiny root and network services needed to get my ...

Finally I found a solution, thank to communities.vmware.com. Maybe this solved only 50% of the cause of the problem, but at least access to the disk can be regained. # esxcli system coredump partition get Active: naa.600605b009a647b01c5ed73926b7ede1:2 Configured: naa.600605b009a647b01c5ed73926b7ede1:2 We see that this coredump partition is using our ...

Dell replace the controller without anything to say that it was the issue? Weird. Tell them the problem still exists and to replace everything. Proc/board/ram until fixed.
