Who, me? Not like I haven't asked for 'em. Or advised that strawman |
| 7 |
case. |

I don't know about "fool," but sometimes even a fool gets lucky...I knew |
| 10 |
squat about XFS, it was just the next thing to try when ext3 ate my |
| 11 |
data... |
| 12 |

Sure but....may I piss on your two-cent epithet first? |
| 16 |
|
| 17 |
I personally run XFS all day long *synced from an ext2 ramdisk* so hey, |
| 18 |
double fool points for me...but I haven't lost 10min of work since...I'm |
| 19 |
very familiar with 'sync' too, no problem flushing at your comfort |
| 20 |
level. |

If power crashes, my disk doesn't crash with it, just RAM. My main |
| 23 |
issue is not having disks spinning when power fails. Basically my disks |
| 24 |
almost never spin - swapoff, RAMdisk, nice tmpfs use. |
| 25 |
|
| 26 |
A database is another thing. It has multiusers, transaction integrity, |
| 27 |
throughput, yada yada. I'm not sure any fs is good 'nuf except ZFS. |
| 28 |
But I would probably use RAID for dbs nowadays. The point is, if you |
| 29 |
have a Biga-bytes database, design and tune, or *you will hurt no matter |
| 30 |
which fs you're using.* |
| 31 |
|
| 32 |
The file system wars blame the wrong targets...the real problems are the |
| 33 |
legacy *nix holdovers like /var/logs and the sort of server mentality |
| 34 |
that goes with them. I love Firefox, but have you ever looked at the |
| 35 |
crazy insane backup behavior? It's unreal - they imitate server cron |
| 36 |
jons. Pretty ugly performance hits. You maybe thought your bookmarks |
| 37 |
were "private" but nooooo. They live in ten different places. And of |
| 38 |
course "profile" management is a sore spot. Because in the legacy |
| 39 |
server mentality, disks don't move around. |
| 40 |
|
| 41 |
I fstablish craptastic legacy server stuff like /var/logs in tmpfs - |
| 42 |
where no disks spin. A server *is* another story. They need disk logs; |
| 43 |
but not desktops. I mean it's absurd. We have L1 cache, L2 cache, L3 |
| 44 |
cache, gigahertz and megabytes, which all goes to waste because *nix |
| 45 |
wants to write /var/logs...the absolute worst single performance killer |
| 46 |
being disk access. So yeah, forgive me if I'm too fond of RAM. |
| 47 |
|
| 48 |
Even Linus himself finally woke up recently about atime option..."hey |
| 49 |
guys, what a ridiculous self-defeating behavior!" or words to that |
| 50 |
effect. It only took 15 years, too... |
| 51 |
|
| 52 |
There is a lot of room for improvement in Linux...sort of at the "wow |
| 53 |
that was dumb" level... |
| 54 |
|
| 55 |
Well bye 'til beta time, then... |
