...ile larger than 2GB on a particular ext3 filesystem. I was under the (mistaken) impression that >2GB support went in before ext3 support, and all ext3 filesystems would therefore support >2GB files on ia32. So, I started poking around and found that some of my ext3 filesystems have the "large_file" feature flag set on them, and others do not. I cannot find a manpage for mke2fs anywhere that explains how to set this flag, either at creation time or afterwards. When I try something like "mke2fs -j -O large_file <dev>" mke2fs complains that it doesn't understand the arg...

Hi, Fedora Core ext3 file systems newbie questions: Just interested in the Linux ext3 features but got confused with "large_file" and "ext_attr". First, what's the "large_file" feature REALLY means? For file systems created with same commands and options some file systems have it on while some not. It is said that the feature is automatic -- If there is a large file then it is lit on otherwise...

...transfered. In a worst case the disk space is running out while this, even if there is enough disk space for a correct sync.

Does Fsync of a file on a ext3 fs mounted with "ordered" option(the default) result in flush the dirty data buffers in the fs that correspond to previous transactions. In other words, if I keep writing to file1 (lots of data), log something to file2, keep fsyncing file2 after every write - does this mean file1 data would be committed by fsyncs on file2. Please copy me on your replies

Hi, I'm about to roll out a whole bunch of Redhat Enterprise 4 workstations and have run into problems cloning from the original. Normally I would use ghost (v7.5) because it does a nice job when cloning to a different sized disk.Unfortunately it comes up with read error 29004. Looking around it seems that Symantec don't support Fedora Core 3 (with Ghost v.8 - don't know if v.9 works

...I am not sure I follow. Let me be more specific. Say you have a trivial stream IO triggering reclaim to recycle clean page cache. This will invoke slab shrinkers as well. Do you really want to drop your batch of pages on each invocation? Doesn't that remove them very quickly? Just try to dd if=large_file of=/dev/null and see how your pages are disappearing. Shrinkers usually scale the number of objects they are going to reclaim based on the memory pressure (aka targer to be reclaimed). -- Michal Hocko SUSE Labs
