Removing a list of Objects
Hi,
I have a simple beginner's question on removing a list of
objects. Say I have objects C243.Daily1, C243.Daily2...C243.Daily5 in my
workspace. I'd like to remove these without using rm five times.
So I write.
> a <- list(paste("C243.Daily",sep="",1:5))
> rm(a)
Obviously this wouldn't work, as it would only remove the object a.
But is there any way

Getting the last day of the month.
...eger(substr(yyyymm,5,6))
if (month==12){
date <- as.Date(ISOdate(year+1,1,1))-1
}else{
date <- as.Date(ISOdate(year,month+1,1))-1
}
print(date)
}
x$Date <- as.vector(sapply(x$YearEnd,GetEOM))
str(x$Date)
Is there a simpler way to do this please?
TIA and best,

Confusion with sapply
Hi,
I have some confusion in applying a function over a column.
Here's my function. I just need to shift non-March month-ends to March
month-ends. Initially I tried seq.dates, but one cannot give a negative
increment (decrement) here.
return(as.Date(seq.dates(format(xdate,"%m/%d/%Y"),by="months",len=4)[4])
)
Hence this simple function:

But now I'm stuck. I don't how to use this list of indices at each row
to exclude my columns.
Any pointers please? Would such an exercise be easier if I use a
time-series based object, like a zoo.

Quick question on merging two time-series of different frequencies
Hi,
A quick beginner's question. I have two time series, A with
daily data, and another B with data at varying frequencies, but mostly
annual. Both the series are sorted ascending.
I need to merge these two series together in the following way: For any
entry of A, the lookup should match with B until we find an entry of B
that's larger than A's.
For all A[i], i = 1,...,N and B[j],

Preserving dates in Excel.
Hi,
Quick question: Say I have a date variable in a data frame or
matrix, and I'd like to preserve the date format when using write.table.
However, when I export the data, I get the generic number underlying the
date, not the date per se, and a number such as 11323, 11324, etc are
not meaningful in Excel. Is there any way I can preserve the format of a
date on writing into a text-file?
TIA

What does gluster do when it's idle?
Hi,
There's no client activity and I have collected tcpdump for 5 mins on one
of the glusterFs sever which is also a client with gluster NFS mount. From
tcpdump I see that for every few seconds, STAT & STATFS commands are run.
For whichctory are these commands being run and why?
Regards,
Jeevan.

What does gluster do when it's idle?
...lls too. I
understood these too calls are to get updated on gluster configuration.
But all these two calls are to a particular node only while there are total
(2+1)*3= 6 nodes in my configuration. Why so? What exactly is DUMP and
PORTBYBRICK?
Regards
Jeevan.

What is the difference between FORGET and UNLINK fops
Filtering the brick logs in TRACE mode with rpcsvc.c does show the FOPS.
>From this, I've realized that LOOKUP is actually dns lookup. This actually
differs from NFS lookup operation. Please correct me if I'm wrong.

stale file handle on gluster NFS client when trying to remove a directory
An ESTALE error usually means the gfid could not be found. Does repeating
the "rm -rf" delete the directory?

What is it with trusted.io-stats-dump?
Hi,
I am trying to understand how the extended attribute trusted.io-stats-dump
works.
setfattr -n trusted.io-stats-dump -v

I can see that the io-stats-pre.txt is created. But how and what happened
in the background?
And why I can't I see the attribute with getfattr again?

What is the difference between FORGET and UNLINK fops
Hi,
Can I get a brief description of all the FOPS in gluster or the location of
the source code file so that I will try to get an understanding myself?
Few FOPS I'm not clear like FORGET, UNLINK, FLUSH, LOOKUP
Or is there a way I can tunnel through the FOPS that that are happening in
the background for each operation? I have tried this to find from a brick
logfile in TRACE mode, but there

Problems with Merge
Hi,
I have a history dataset, a matrix with about 1590 obs, and 242 cols,
and I need to update this matrix with an 'update' matrix that has about
30 rows, and roughly similar number of columns as the history ds (but
not necessarily equal). The update dataset is read from an Excel ODBC
connection. When I try and merge these datasets, I get counter-intuitive
results.

stale file handle on gluster NFS client when trying to remove a directory
Hi,
After running rm -rf on a directory, the files under it got deleted, but
the directory was not deleted and was showing stale file handle error.
After 18 minutes, I'm able to delete the directory. So could anyone help me
in knowing what could have happened or when in general I get such errors.
The following is NFS log:

Samba limitation to concurrent open files
Can Samba handle in the range of 1million to 3 millions concurrently open
files? If so, then from which Samba version onwards?
Does it have any benchmarking results on maximum number of open files that
Samba can have concurrently?
Any reply to this question is highly appreciated.
Thanks in Advance

...s://github.com/bengland2/gluster-profile-analysis
It doesn't have some of the ones you are looking for but if you get
definitions of what they are I would like to add them to what we have in
the profile analysis tool's README.

What is it with trusted.io-stats-dump?
...s-dump
gets bypassed at the io-stats translator layer on the stack and
there it gets converted into the action of dumping the statistics into the
provided output file path.
See io_stats_setxattr() implementation in io-stats.c for more details.
