Re: snapshots on large filesystems
Not enough info to be entirely informative in my reply, but I'd look to rsync or something similar... copy data/snapshot to another machine. We're running a similar setup here using 250GB S-ATA RAID Edition drives and 3Ware Escalade 9000-series controllers, a second machine simply rsync's the data from the first nightly... was cheaper to have whole second raid setup and dedicated gigabit ethernet from one machine to the other than was to invest in tape backup devices/media. In addition we do a bi-monthly snapshot on an external USB drive (via tar direct to device... not reccomend cause' it's slow, looking for a faster way myself to do that). With the cost of 200+GB drives, and applicable decent performing raid cards... it's just cheaper in most cases to mirror the data on another machine. - but that's just my two cents ;) -- Nathan Vidican [EMAIL PROTECTED] Windsor Match Plate Tool Ltd. http://www.wmptl.com/ user wrote: Hello, Considering a PC server running FreeBSD with 4 400 GB hard drives attached to a hardware raid controller doing raid-5.

Given current disk capacities, I would not exactly consider this 1.2TB filesystem a large one ... any comments on say ... a 6-8 TB filesystem and making one or more snapshots of it ?

I've got a 283Gb partition, and the system was trying to create the snapshot for 12 hours. I'm on 5.4-RELEASE. Should this be taking this long? My gut tells me no...cause it'd be foolish if it did. Any ideas/suggestions? No, it shouldn't. It appears that there is some problem with the snapshot process on large filesystems in 5.4-RELEASE and perhaps others, but I don't know how aggressively it is being investigated, or whether a solution has already been found. There have been several posts about this in the past month or two, if you search the archives you might find better information about it. I remember there was conjecture about the possible cause (e.g. insufficient temporary storage space for the inode list), but I don't remember if this led to a workable solution. - Bob ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: snapshots, soft update inconsistency
Jay [EMAIL PROTECTED] writes: I've got some filesystem problems on my /usr partition. Cause: power failures caused by TWO exploding transformers I restarted in single-user mode and fsck'd all of my partitions. Everything looked fine. I've got a handful of zero-length files that I can't fix. Bad file descriptor. I've tried `ls -i` to get the inode number so I can delete the files via find. ls doesn't work -- it just returns Bad file descriptor. I then had the bright idea of making a snapshot and running fsck against it. I got a few hundred lines of unexpected soft update inconsistency. I didn't have fsck repair anything against the snapshot; I just wanted to see what the output was. Should I: a) run fsck against the snapshot and let it fix things b) go back to single-user mode and run fsck c) do something else I'm sure that booting into single-user mode is the best idea, however, I'd prefer not to do that if possible -- the machine is up and running and doing it's thing fairly well at the moment. I thought you said you had already done that, and that it seemed fine. Doing it again will only help if new problems have arisen since then. If the machine is working okay as it is, and the data on its disks is completely expendable, then feel free to leave it alone and wait for problems to get worse. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
