When its mounted the permissions change to this: ls -ld /projects drwxr-sr-x+ 13 reader man 14 Jul 25 09:47 /projects Whats with the `man' group? The way nfs works is that it takes a remote filesystem and *mounts* it locally, exactly as if it were a local filesystem. It is not a share. The inodes are exported over nfs and that directory is owned by a group with gid of say X. On your local machine that gid just happens to be the man group. There is nothing much you can do about this except: Renumber your gid's locally to match the nfs server, or renumber the nfs share gids to match your local machine Also, when mounted I find when I try to copy somethihng with the -a option, which tries to maintain any permission settings. It causes an error warning... (although the copy is done). cp -a file file1 cp: preserving permissions for `file1': Operation not supported Full paths please. I can't see which way the copy is going. I suspect that your user on the nfs server is not a member of the group that has the same gid as your local man group. And the files permissions end up: ls -l file* -rw-r--r--+ 1 reader man223962 Jul 26 15:56 file -rw-r--r--+ 1 reader reader 223962 Jul 26 15:56 file1 Is there some way to set it up so that permissions can be copied? Also to alow the set-gid setting to work? Golden rule with nfs: It was designed for the case of a diskless client mounts it's home or root directories over the network, while exporting passwd and shadow files over NIS. That is evident in it's design and there is no facility to change uids and gids on the fly. You do not authenticate with nfs, the server assumes that the request coming from the client is OK and treats it exactly as it would a request from a local user on a local disk. This is the primary reason why nfs performs so well. It is up to you to make sure your uids and gids everywhere match and work. nfs cannot and will not help with this. -- alan dot mckinnon at gmail dot com

Best??? ;))) Well, I haven't tried it under Linux, and I'm afraid I can't easily do so either. I'll also disclaim myself as not an expert by any means on the subject of webcams, but to my eyes the picture was really good when I tried it with the PS3 and on Windows. I think I compared it with my Macbook's built-in webcam (Windows XP, Apple's bootcamp drivers) the Playstation Eye was better (also XP, 3rd-party hacker's drivers). I have seen the output of plenty of cheap nasty webcams, and I would say this is in a better class. For your application the quality of image indoors in low-light (which I think is quite good) may not be an advantage; you may find both zoom settings may be quite wide. But this camera seems quite good quality and feels well made; Linux drivers are available although I've no idea how good they are. I mentioned this cam in my previous message because I read that it maxes out the USB bus. But if you want to play around with webcams, it can also be picked up quite cheaply - I paid £20 for it (included with the Eye of Judgement card game) at Christmas, and I've seen it more recently for £25.

You don't need to buy SSD drives - instead you could use CF cards and a cheap adaptor.

I don't know how that really compares to RAID 1 - if you use hardware RAID (and you can get hardware SATA controllers for £50 these days) then you can assign a hot-spare, and hot-swap a replacement drive with zero downtime. With hardware RAID you can still boot if one of the drives fails, but you do add the controller as a potential point-of- failure. Stroller.

So I guess the set-gid only needs to be set on the exported directory. In fact, I would set the permissions of the mount point so that it's only writable by root so that ordinary users can't write to it while it's unmounted (a later mount would make those files invisible for as long as the directory is mounted). And finally: Using the kernel automounter (autofs) avoids 1) the need for the users option 2) users forgetting to mount the thing Bye...

[gentoo-user] LiveCD installation not recognizing megaraid RAID set
I was trying to put gentoo on a dell poweredge 1950 quadcore xeon machine with three disks connected to a lsi PERC 5/i raid controller. In the BIOS settings, all three disks were added to the controller for a RAID5 set up. When I boot from LiveCD (2008 version with 2.6.24-r5 kernel) with dmraid='-ay' option, it came up not recognizing the RAID set, as I only saw control under /dev/mapper. modprobe megaraid was okay, so was modprobe raid5. Under /dev, I only saw sda, but there was no sdb, sdc. So it looked like there was only one disk but the system did not recognize it as a raid set. Booting from LiveCD with dmraid='-ay' doscsi didn't help. I got the same result. If I did a dmraid -ay in bash, I got No RAID disks. Could anyone point me to some instructions on how to make Gentoo recognize the PERC 5/i RAID controller? I tried both 32bit and 64bit gentoo and results were the same. lspci showed: 02:0e.0 RAID bus controller: Dell PowerEdge Expandable RAID controller 5 dmesg showed: megaraid cmm: 2.20.2.7 (Release Date: Sun Jul 16 00:01:03 EST 2006) megaraid: 2.20.5.1 (Release Date: Thu Nov 16 15:32:35 EST 2006) megasas: 00.00.03.10-rc5 Thu May 17 10:09:32 PDT 2007 megasas: 0x1028:0x0015:0x1028:0x1f03: bus 2:slot 14:func 0 ACPI: PCI Interrupt :02:0e.0[A] - GSI 78 (level, low) - IRQ 17 megasas: FW now in Ready state scsi4 : LSI Logic SAS based MegaRAID driver scsi 4:0:0:0: Direct-Access SEAGATE ST973402SS S206 PQ: 0 ANSI: 5 scsi 4:0:1:0: Direct-Access SEAGATE ST973402SS S206 PQ: 0 ANSI: 5 scsi 4:0:2:0: Direct-Access SEAGATE ST973402SS S206 PQ: 0 ANSI: 5 QLogic Fibre Channel HBA Driver scsi 4:0:8:0: Enclosure DP BACKPLANE1.05 PQ: 0 ANSI: 5 scsi 4:2:0:0: Direct-Access DELL PERC 5/i 1.03 PQ: 0 ANSI: 5 scsi 4:0:8:0: Attached scsi generic sg1 type 13 sd 4:2:0:0: [sda] 284164096 512-byte hardware sectors (145492 MB) sd 4:2:0:0: [sda] Write Protect is off sd 4:2:0:0: [sda] Mode Sense: 1f 00 10 08 sd 4:2:0:0: [sda] Write cache: disabled, read cache: disabled, supports DPO and FUA sd 4:2:0:0: [sda] 284164096 512-byte hardware sectors (145492 MB) sd 4:2:0:0: [sda] Write Protect is off sd 4:2:0:0: [sda] Mode Sense: 1f 00 10 08 Thanks very much for your help! -- -hoki

Your RAID set is being detected by the LiveCD. It looks as though you have a RAID5 set using 3x72GB drives. This would be consistent with the size of /dev/sda (144GB). Because it's hardware RAID, operating systems don't usually access each individual disk but rather the disk set presented by the controller. As mentioned by Neil, dmraid is for software RAID management. If you want to manage your RAID controller or disk sets from Linux, you'll have to find management software capable of doing this. Try the server manufacture's site or the RAID manufacture's web site to see if such software exists. Hope that helps, Carlos

So it looked like there was only one disk but the system did not recognize it as a raid set. It looks like *not only* did you add them to the controller, but you configured them as a single drive.

First, check the info and forums at http://www.quickcamteam.net/ if you have not already. Lots of good info and Logitech developers there. Try to disable the auto exposure and low-light features. It really kills the frame rate. CPU load of processing and displaying live video is also prohibitive on slower hardware. I have a Quickcam Pro 9000 which I believe is very similar to the notebook version you have, maybe the same chipset. I, too, was very disappointed with the video quality considering the reviews, the marketing HD video 1600x1200, and the cost. I expected it to look like a camcorder, but it is basically crap. I even attached it to a Windows machine using the official Logitech drivers and software and it is equally unimpressive. Based on all of the reviews online it seems this is one of the best consumer webcams (without getting into very expensive professional equipment). In a dim room, even with normal indoor lighting, I get about 5fps with the auto-exposure/low-light features enabled. With bright light it's about 15fps. Disabling those features should give you the highest frame rate but, of course, they make the image look much better at the expense of frame rate. It has been a very long time since I used it but I think all of these settings were able to be controled via luvcview for testing. Good luck, I think I had some hairs turn gray trying to make it look good...
Re: [gentoo-user] {OT} SSD instead of RAID1?
Grant schrieb: ... What if I bought a low-price/low-capacity SSD drive for each of these systems, installed the system essentials on them, and used my existing high-capacity HD drives for data storage? Would each system keep running if the HDs died? If so, I think that would offer as good or better system reliability than RAID1. What do you think? You don't need to buy SSD drives - instead you could use CF cards and a cheap adaptor. These are commensurate in capacity cost with USB flash drives (4gig, maybe 16gig?), but CF cards talk EIDE and you can get cheap pin-convertors allowing you to connect them to EIDE cables and treat them like a hard-drive. Aren't CF cards much slower than SSD drives and HD drives? Yep, especially the cheap ones which do not support DMA, just PIO. But this is not necessarily a problem: After starting all services etc. there will be very few reads on stuff like /etc and /usr. Just make sure to put all directories to which you write (parts of /var like /var/log and the several tmp directories) on an HDD, NFS or tmpfs. Of course, this all depends on your usage patterns and how much RAM you have. If you really need to write to the CFDisk, make sure to buy one with DMA support (and no, the label super fast which is regularly found on these things does not necessarily mean that it supports DMA). One drawback of this configuration: You can never use swap - never! Neither on the HDD (there is a high chance that the system would crash when the HDD fails) nor on the (cheap) SSD/flash drive (the drive would wear down, removing any advantage you tried to gain). I know of these used in Asterisk based PABX systems PoS tills with the expectation that they're more reliable than disks, and have read statements by people deploying quantities of such machines that they've never had a failure in years of use. I like the sound of that. Where I work, we have a System-on-a-Chip (SoC) NAS. Albeit being the second most powerful machine we have in our server room (quad core CPU, lots of RAM, three redundant power supplies and a good dozen HDDs), the OSS itself resides on a removable card not bigger than my thumb. I don't know how that really compares to RAID 1 - if you use hardware RAID (and you can get hardware SATA controllers for £50 these days) then you can assign a hot-spare, and hot-swap a replacement drive with zero downtime. With hardware RAID you can still boot if one of the drives fails, but you do add the controller as a potential point-of-failure. Would the system keeping running if I used a CF or SSD for the system install and the HD drive died? - Grant signature.asc Description: OpenPGP digital signature

One thing to watch out for if you do go the CF/DMA route - be careful what CF-IDE/SATA adapter you buy - in an embedded control system project I worked on a few years ago, we went CF + adapter for the primary OS driver, got a super-fast 4GB CF card, and couldn't use the speed of it at all, because the cheapo CF adapter we got was so electrically noisy across the physical adapter pins, that DMA reads/writes would fail, and the speed would get auto-reduced to PIO. Very, very, very annoying. If you get a CF adapter, make sure to spend the extra $5-20 (or however much, I haven't priced in quite a while) to get something that will be compatible with the transfer speeds that you are wanting to use. -James
