Hi Jörg! I hope you can tell something about.
I mentioned something strange. I add a partition (DH11) with HDInstTools 10 days ago. The whole last range of the HD. Until now I used it only for recordings with AHIRecord what writes 256kb at once (editable) to the file. That worked fine until now. Suddenly AHIRecord start writing 256kb and then hangs. I can reboot an start AHIRecord what wirts another 256kb file and hangs. On other partition (eg. DH4) it works well. I thought maybe someting is full or think so. Then I delete .recycled dir (about 8GB) on DH11 and tried AHIRecord again. Now it works. It would be a pitty if this happens again. On my other (nearly full) partition (DH4) with SmartFilesystem 2.3 (28.09.00) I never had such a problem. Einheit Größe Genutzt Frei Voll Fhlr Status Typ Name DH4: 12,9G 12,3G 624,4M 95% 0 schr.-/lesbar SFS2 Rec Here the problem partition: Einheit Größe Genutzt Frei Voll Fhlr Status Typ Name DH11: 27,2G 8,0G 19,3G 29% 0 schr.-/lesbar SFS0 Rec2 SFSquery information for dh11: (SFS Version 1.279) Start/end-offset : 0x0000000b:d3234000 - 0x00000012:a1f16000 bytes Device API : NSD (64-bit) Bytes/block : 512 Total blocks : 57108240 Cache accesses : 30688 Cache misses : 24855 (80%) Read-ahead cache : 8x 8192 bytes (Copyback) Flush timeout : act. 20s - inact. 0.5s Max Name Length : 107 DOS buffers : 150 SFS settings : [RECYCLED] SFSCheck: Partition start offset : 0x0000000b:d3234000 End offset : 0x00000012:a1f16000 Surfaces : 1 Blocks/Track : 324 Bytes/Block : 512 Sectors/Block : 1 Total blocks : 57108240 Device interface : NSD (64-bit) Checking RootBlocks ...okay Checking AdminSpaceContainers at block 2 ...okay Checking NodeContainers at block 7 ...okay Checking ObjectContainers at block 3 ...okay Checking Bitmap at block 34 (14278 blocks, 4000 bits/bitmap) ...okay |

Alas I have to report that I got the same problem again. After deleting some files from .recycled it worked again.

"Cache accesses : 30688 Cache misses : 24855 (80%) Read-ahead cache : 8x 8192 bytes (Copyback) Flush timeout : act. 20s - inact. 0.5s Max Name Length : 107 DOS buffers : 150 SFS settings : [RECYCLED]" 150 dosbuffers on a ~30 GB partition? no way! |

>150 dosbuffers on a ~30 GB partition? no way! Do you mean that the amount of 150 dosbuffers are responsible for the problem? I would use a higher amount but I`ve only 32MB available. Thats the reason for the 150 buffer. :( |

up it at least to 300 i may be wrong but remember reading somewhere it's the least amount of buffers when you use SFS partitions. I have a 25GB partition here using it with 400 buffers and never ever had problems with it ...although, i may probably be wrong ... waitign for joerg to pop in ![]() |

400 dosbuffers with a 25 GB partition? your using SFS at 40% of its potential!! try a SFSQuery and look at how many caches missed you get. |

@daxb
if you use that partition for HD recording, set the partition blocksize to 1024 with 1000 dosbuffers and without .recycled Use SFSFormat with the NORECYCLED option i.e: SFSFormat DEVICE xxx: NAME foo NORECYCLED Edit- btw just noticed this bit: "I mentioned something strange. I add a partition (DH11) with HDInstTools 10 days ago" have you always used HDInstTools for ALL partitions on that HD? Edited by Framiga on 2008/3/23 13:39:08

@Raziel
"so" you have no enough dosbuffers! 0% is what you should achieve. (look at the 80% of caches missed from the above reported sfsquery) Of course you have to test with sfsquery, accessing the partition after some minutes. |

I can live with 10% cache misses on the upside of having more RAM for more important tasks... |

Uhm, why? It works, even with 99% cache misses it would work, it would just have to access the drive more often... |

efficency, reliability, performance ... have you checked fragmentation onto your SFS partition for example? |

yes ... close to nothing after months of usage by far better than other fs after defragmentation ![]() |

Quote: I can live with 10% cache misses on the upside of having 10% cache misses is a lot, if you get more than 1% cache misses (after using the partition as usual for some time, don't check it for example directly after (re)booting) SFS is already much slower than it could be. On classic Amigas with only a few MB RAM using enough buffers may not be possible, but on the AmigaOne, or a CSPPC with 128 MB or a BPPC with 256 MB RAM, it's not, you usually only need a few KB more RAM for the buffers of each SFS partition to get much faster speeds, not several MB. |

"@Framiga >150 dosbuffers on a ~30 GB partition? no way! Do you mean that the amount of 150 dosbuffers are responsible for the problem? It shouldn't, it's only much slower than it could be with that few buffers." nope, not necessarly. I was poiting out that beeing the user using a misconfigured SFS for HD recording (with recycled) the dosbuffers could be part of the problem. Or more simply he have an HD full of bad blocks. btw ... do you thik is a good idea using SFS with a slighty larger blocksise (1024-2048) for HD recording? (still without .recycled) About Raziel i still don't uderstand if he is speaking about AOS4 on AOne or Classic! ![]() |

Understood, though you don't say what would be a good buffers setting for, lets say 256 MB 500 MB 1 GB 5 GB 10 GB 25 GB 70 GB partitions...(that being my partition sizes) @Framiga Quote:
Check my extra info, i try to port stuff, thus needing every byte of RAM i can get (until VMEM pops up ![]() |
