similar to: InterMezzo patch for ac?

Hi Stephen, We had some starvation/locks happening to us under very heavy load in two cases: - InterMezzo asked ext3 to do a journaled file write (for 1 block) essentially using ext3_write - similarly for truncate. These lockups went away when we started the transaction in InterMezzo and reserved somewhat more space than ext3 does. Any clues as to what this might be? Are the ext3

Hi, We have encountered another funny with ext3 on 2.4. Like the kernel NFS server, we have a routine in InterMezzo that does something like looking up an inode by inode number. (compare intermezzo's presto_ilookup or knfsd's nfsfh_iget) Effectively both of these routines do ilookup() { inode = iget(sb, ino) if (inode->i_nlink==0) iput(inode); .... } We find that

(It was suggested I send a copy of this to ext3-users, so here it is - note that I need this RAID going so I've rebuilt with reiser, but would still appreciate suggestions; the message was original sent to the lkml) Hi, I've just built an 800GB RAID5 array and built an ext3 file system on it; on trying to copy data off the 200GB RAID it is replacing I'm starting to see errors of the

hi, is this rpms differ from redhat's rawhide 2.4.5 kernel which seems to contain ext3. so my question that your rpm contain different ext3 than rh's rpm? or I can simple use rh's rawhide rpms? thanks. yours. ps. please reply to my private address to since I'm not on the list. thanks. > Hi, > > Mostly for my own use, I prepared two kernel RPM's with Ext3 in them.

Greetings, I'll keep this as brief as possible: Is Redhat going to support ext3 or reiser (or both) in the next version of Redhat (I'm not looking for a commitment, just a roadmap)? I noticed (and used) the reiser utilities in the Wolverine beta (on a test box) to make reiser paritions, but upgrading to the 7.1 release failed as it only saw ext2 partitions. I understand that ext3 is

Unfortunately it is a bit more complex, and the truth is less complementary to us than what you write. Reiser4's CPU usage has come down a lot, but it still consumes more CPU than V3. It should consume less, and Zam is currently working on making writes more CPU efficient. As soon as I get funding from somewhere and can stop worrying about money, I will do a complete code review, and

Hi, I have a detailed question about ordered data writes. Suppose we (i.e. intermezzo) does a transaction, which is closed and then followed by an ordered write. Let's assume the ordered write doesn't require new allocation metadata. Is the write still postponed until the first transaction has committed? As far as I can see, prepare_write always starts a transaction, but I'm

Hi, While doing some stress testing with presto module from the intermezzo project layered over ext3, I got the following assertion failure: Jan 17 23:09:55 planck kernel: Assertion failure in jfs_prelock_buffer_check() at journal.c line 410: "bh->b_jlist == 0 || bh->b_jlist == BJ_LogCtl || bh->b_jlist == BJ_IO || bh->b_jlist == BJ_Data" Jan 17 23:09:55 planck kernel:

Hi! Are these results i got from my benchmarking "normal" or is there something strange happening in my system? This box is going to be a mailserver, so i tested various fs to decide on which i should utilize. I personally dislike reiserfs because it has proven somehow unreliable on our servers (although it got better in the more recent kernels), ext3 would be quite good (fsck'ing

I guess we're just circling around the main issue here: it's great you really like Reiser and think it's k3wl or whatever, but this isn't the place to come tell us about

Hi, A system running ext3 crashed this afternoon (nothing to do with ext3, bad network driver). Is was saving a file from emacs when it happened. The file system is 0.06b and had ordered data as the mount option. Let me emphasize this was running ext3 pure, not with SnapFS or InterMezzo layered on top of it. strace reveals that Emacs does open("existing file name", O_TRUNC |

Hello, recently Theodory Tso posted a patch for the ext2fs driver, which improves speed of find and similar programs. Background: the application access all entries in the directory in the order they are stored on the disk. The current ext2 (and apparently Ext3) run a lookup function for each readdir call, starting with the first node! Theodore stores a refference to the node which was accessed

Hi, where do I get Alan's 2.4.8-ac?-Kernels including ext3. I only found patches. I could not patch them into my kernel (2.4.4-SuSE, Kernel from SuSE 7.2, patched by them). Should I download plain 2.4.8 and path the pathes into it? Which? How? Or is there a tar.gz / tar.bz2 including these patches? I would try ext3. Rene

Hi, I am upgrading the tomsrtbt rescue distribution from kernel 2.0.39 to 2.2.20. Fitting a 2.4.x kernel on the floppy is not practical at this time. I am trying to support both ext3 and reiser filesystems. However, there are symbol collisions, it is impossible to use both. Is there any chance of getting the 2.2.x patch fixed? -Thanks -Tom

Hello ext3 users and developers, I am gathering information for an article about journal filesystems with emphasis on write barrier functionality, how it works, why journalling filesystems need write barrier and the current implementation of write barrier support for different filesystems. Background of this is my own experience of three XFS crashes in one week:

Forgive me if this has been discussed. I'm new to the list and couldn't find any list archives or a FAQ or anything similiar. (Is there anything?) I've just today installed ext3 .5d in my machine. All drives (including '/'). I like it! However, I'm curious about what it's doing. I don't know C, so telling me to read source won't help. I'm wondering if it

I've lurked on this list for a long time, and have learned many details on installing and using Ext3. Thanks! I'm finally posting to solicit feedback on my recently-published book on "Linux Filesystems". This book discusses the use, theory, and installation/integration of journaling and distributed filesystems on Linux, and also discusses what I call 'filesystem adapters'
