I am using following PowerShlell to get the list of available physical disk.
$disks=((Get-PhysicalDisk -CanPool $true)|Select-Object PhysicalLocation)
The output of above code is as shown below
Integrated : Adapter 3 : Port 0 : Target 0 : LUN 7
Integrated : Adapter 3 : Port 0 : Target 0 : LUN 0
Integrated : Adapter 3 : Port 0 : Target 0 : LUN 5
Integrated : Adapter 3 : Port 0 : Target 0 : LUN 2
Integrated : Adapter 3 : Port 0 : Target 0 : LUN 6
Integrated : Adapter 3 : Port 0 : Target 0 : LUN 4
Integrated : Adapter 3 : Port 0 : Target 0 : LUN 1
Integrated : Adapter 3 : Port 0 : Target 0 : LUN 3
Integrated : Adapter 3 : Port 0 : Target 0 : LUN 8
However, form the collection I want to select a set of LUN e.g LUN from 5 to 8 to create a storage pool using
New-StoragePool
Thanks
You don't need to put the expressions in parenthesis. You can try something like below. This regex will help you to get the desired result.
Get-PhysicalDisk -CanPool $true | Foreach-Object -Process {
$_.PhysicalLocation | Select-String -Pattern 'LUN.[5-8]'
}

I have a script that copies a file from a network location to a local folder using robocopy.
When I run following powershell 7 script from Visual Code, or execute the command directly in PS, only 1 file is copied as intended. If a run the script in powershell 4 files are copied. How can I copy the single file running from the script.
$dbname = "domoticz.db"
$sourcedir="\\ix2\PiBackup\domoticz\"
$targetdir="C:\tmp\DomoticzScripts\"
$dbfile = $targetdir + $dbname
robocopy $sourcedir $targetdir $db -njh
Output running it directly or VS Code debugger

I believe you need to set the IPsec phase 1 and 2 algorithms to the same as what the VPN server is using, or reconfigure the VPN server to offer stronger proposals.

You're dealing with strings ([System.String]), not [System.Objects] - the latter is only the base type, i.e., what [System.String] derives from.
The best way to compare 2 multiline strings is to compare them line by line, and to that end you must split them into an array of lines:
PS> Compare-Object ($abc -split '\r?\n') ($def -split '\r?\n')
InputObject SideIndicator

10.46.252.121 4 7251 0 0 0 0 5d23h Connect <=
The => lines (the .SideIndicator property value of the output objects representing differences) indicate lines exclusive to the RHS ($def) whereas <= indicates lines exclusive to the LHS ($abc)
I'm using TraMineR to inspect work trajectories.
When using the seqformat function (from SPELL data) with process = TRUE, and an external data frame for pdata, as follows :
situations <- seqformat(data[,1:4], id = 1, from = "SPELL", to = "STS",
begin = 3, end = 4, status = 2, right = NA,
process = TRUE, limit = 7644, pdata = pdata,
pvar = c("id","birth"))
I get an error message :
Error in charToDate(x) :
character string is not in a standard unambiguous format
I read many threads about that issue, but could not find any helpful solution.
Here are the structures of my data frames data and pdata :
str(data)

It seems to me that all date formats are OK.
But, clearly, something's wrong.
What am I doing wrong?
Thank you in advance for your help,
Best,
Arnaud.
The seqformat function expects integer values for the begin and end dates of the spells. Actually, these integers should be the (time-)position in the state sequence and will correspond in your example to column numbers in the resulting STS format.
So you need to transform your dates into integer values.
=============
The error
Error in charToDate(x) : character string is not in a standard unambiguous format
occurs while the function tests whether pdata is the string "auto" with if(pdata == "auto"). This is because, when pdata contains dates, the test attempts to coerce "auto" into a date for the sake of comparison. The workaround is to input the dates as integers.
We have a MongoDB collection containing nearly 40 million records. The current size of the collection is 5GB. The data stored in this collection contains following fields:
_id: "MongoDB id"
userid: "user id" (int)
mobile: "users mobile number" (int)
transaction: "transaction id" (int)
sms: "message sent to user mobile" (text)
created_dt: "unix timestamp of the transaction"
Apart from the index on _id (created by default), we have defined separate indexes on the mobile and transaction fields.
However, the following query takes anywhere between 60 to 120 seconds to complete:
{
mobile:<users mobile number>
}
I access MongoDB using RockMongo. MongoDB is hosted on a server with 16GB RAM. Nearly 8GB RAM on this server is free.
What is it that I am doing wrong here?

Update 2:
Until recently, we used to store another collection with about 1.3 billion documents in the same MongoDB server. This collection has now been removed (dropped). This may explain the mapped / vsize column in above output from mongostat.
The server also stores 6 other collections which have frequent inserts. The total storage size currently is about 35GB.
Update 3:
Indexes defined on the collection. Created using RockMongo.
[
{
"v" : 1,
"key" : {
"_id" : 1
},
"ns" : "mymongodb.transaction_sms_details",
"name" : "_id_"
},
{
"v" : 1,
"key" : {
"_transaction_mobile_" : 1
},
"ns" : "mymongodb.transaction_sms_details",
"background" : 1,
"name" : "mobile"
},
{
"v" : 1,
"key" : {
"_transaction_transaction_" : 1
},
"ns" : "mymongodb.transaction_sms_details",
"background" : 1,
"name" : "transaction"
}
]
The keys generated by RockMongo is apparently incorrect.
"_transaction_mobile_" : 1
"_transaction_transtion_" : 1
I don't know what's wrong with RockMongo, but I think this can fix the issue:
db.xxx.dropIndexes();
db.xxx.ensureIndex({mobile: 1});
db.xxx.ensureIndex({transaction: 1});
Notice: This may take VERY LONG time. Don't do this on a running production machine.
