similar to: ZFS replication send/receive errors out

So, I was running my full backup last night, backing up my main data pool zp1, and it seems to have hung. Any suggestions for additional data gathering? -bash-3.2$ zpool status zp1 pool: zp1 state: ONLINE status: The pool is formatted using an older on-disk format. The pool can still be used, but some features are unavailable. action: Upgrade the pool using ''zpool

First, it fails because the destination directory doesn''t exist. Then it fails because it DOES exist. I really expected one of those to work. So, what am I confused about now? (Running 2008.11) # zpool import -R /backups/bup-ruin bup-ruin # zfs send -R "zp1 at bup-20090222-054457UTC" | zfs receive -dv bup-ruin/fsfs/zp1" cannot receive: specified fs (bup-ruin/fsfs/zp1)

Hmm, bup uses the fchdir() syscall to go into the target

Hi, I feel that i'm having a small problem with my upsmon configuration (maybe even simply a permissions problem) since I upgrade today to 2.0.2 I have apcsmart set up and talk to my ups no problem (upsc get answer). I have upsd running no problem! But when I try to start upsmon, it's unable to talk to my upsd. Having try a few option I found that saying RUN_AS_USER=root makes my upsmon

At the risk of ridicule for my deficient linear algebra skills, I ask for help using the solve.QP function to do portfolio optimization. I am trying to following a textbook example and need help converting the problem into the format required by solve.QP. Below is my sample code if anyone is willing to go through it. This problem will not solve because it is not set up properly. I hope I

I have now tested with `performance.stat-prefetch: on` but am not observing a difference. So far the only difference between `ls` and `bup index` I could observe is that `bup index` chdir()s into the directory to index, ls doesn't. But when

Hi, I have a gluster 3.10 volume with a dir with ~1 million small files in them, say mounted at /mnt/dir with FUSE, and I'm observing something weird: When I list and stat them all using rsync, then the lstat() calls that rsync does are incredibly fast (23 microseconds per call on average, definitely faster than a network roundtrip between my 3-machine bricks connected via Ethernet). But

I did a quick test on one of my lab clusters with no tuning except for quota being enabled: [root at dell-per730-03 ~]# gluster v info Volume Name: vmstore Type: Replicate Volume ID: 0d2e4c49-334b-47c9-8e72-86a4c040a7bd Status: Started Snapshot Count: 0 Number of Bricks: 1 x (2 + 1) = 3 Transport-type: tcp Bricks: Brick1: 192.168.50.1:/rhgs/brick1/vmstore Brick2:

I found the reason now, at least for this set of lstat()s I was looking at. bup first does all getdents(), obtaining all file names in the directory, and then stat()s them. Apparently this destroys some of gluster's caching, making stat()s ~100x slower. What caching could this be, and how could I convince gluster to serve these stat()s as fast as if a getdents() had been done just before

Dear list, I am syncing files with rsync .... surprise surprise ...

Hi. Dovecot 2.2, with the zlib plugin, I think we're getting bad index entries on IMAP COPY. On copying a message to an empty folder, in the dovecot error log I see: Sep 19 20:34:25 imap01 dovecot: imap(grain at rp-auth-test.com): Error: Cached message size smaller than expected (615 < 971) Sep 19 20:34:25 imap01 dovecot: imap(grain at rp-auth-test.com): Error: Corrupted index cache file

WHY OH WHY does rsync SEND and CREATE a file called RepositoryPath ALTHOUGH the rsync is called like rsync "--exclude=*.bup RepositoryPath" ... can ANYBODY explain. ALSO when you specify an exclude list on the server in the rsyncd.conf file and you call rsync with the --delete option WHY DO THE FILES that SHOULD BE EXCLUDED get deleted ?? Jeeez, what a bummer W

I'm attempting to mirror a directory tree from debian stable (rsync version 2.5.6cvs) to a win2k box (cygwin, rsync version 2.5.5). This setup/command had previously worked for a bit (cygwin at rsync version 2.4.6 AFAICR), but yesterday it hung, so, finding some mail-list entries about that, I upgraded cygwin, and now I get this: C:\>c:\cygwin\bin\rsync.exe -vvvvvv -essh -ac --delete

Not yet, because I'm still struggling to understand the current more basic setup's performance behaviour (with it being off), but it's definitely on my list and I'll report the outcome.

Hi All, Today I got a couple of ZyXEL Prestige 2000W WiFi phones. I'm having a problem making SIP calls although I can receive calls just fine. When I try to make a call the phone makes some sound (like "bup bup bup bup bup bup beep beep") and then I just hear hissing background noise (not too loud - like comfort noise). I upgraded to the latest firmware on the phone - Wj.00.10

Hi David, in my opinion, VDO isn't worth the effort. I tried VDO for the same use case: backups. My dataset is 2-3TB and I backup daily. Even with a smaller dataset, VDO couldn't stand up to it's promises. It used tons of CPU and memory and with a lot of tuning I could get it to kind of work, but it became corrupted at the slightest problem (even a shutdown could do this, and

Folks I'm looking for a solution for backups because ZFS has failed on me too many times. In my environment, I have a large amount of data (around 2tb) that I periodically back up. I keep the last 5 "snapshots". I use rsync so that when I overwrite the oldest backup, most of the data is already there and the backup completes quickly, because only a small number of files have

Dear R-experts, I have a data file df as the following: genename variable at 1hr variable at 4 hr variable at 10 hr gene1 gene2 . . . gene5000 I would like to have a graph with X-axis as the time point (1hr, 4hr, 10hr), and Y-axis as the value of the variable. So, basically, I want to do a line with the three different values at 1hr , 4hr and 10hr for all the 5000 genes. My purpose is

Is there a way to timeout POP3 query if they come to often? More precise I want to know if there is a setting in dovecot that makes it ignore pop3 requests from a certain user if they come more often then a certain amount of time. I am looking for a setting in dovecot, not a firewall solution. I would like dovecot to answer something like "requests come to often, please come back
